Well I did impressions of Move a while back, I actually bought that device cause it was within my price range and has a few games that interested me, my day with Kinect was over at my friends place, he only had a couple of games and had to play them together with everyone so it won't be as complete as my Move impressions, mainly because the best looking games Dance Central and Kinectimals wasn't there.

Device:

First thing right off the bat, the device needed space, for the average home or apartment, a bit too much, we had to stand with our backs up against his dresser just to be in the recommended range, his room was much larger than my room and had more space than his living room, that's going to be a problem if you're trying to market to the average family, IE the mass market.

Two, you don't have instant responses when picking options, this might be a nit-pick for some people, for me it isn't, having a B/circle/back button is a nice thing, its instant, its there, and lets to navigate menus quickly.  Kinect?  Hold your arms in a position for a few seconds to pull up a menu, see the option you want to choose, move your hand over there, hold it for a few more moments, rinse and repeat for every option you want to choose.

Number three there is a noticeable lag, like there was a slight lag with Move but Kinects lag can actually interfere with games in a major way.  Playing Kinect Adventures' Reflex Ridge which actually does require timing you'll come to places where you have to jump and duck, you can jump right before the obstacle comes all day long you'll still hit the thing, jumping right before is the natural thing to do but what you have to do is account for the lag and jump about a second before the obstacle cause then it registers your jump and you'll jump over it, same could be said about any other obstacle but unlike ducking to get ready for a obstacle coming at you, you simply can't hang time to make sure you're in the air for it gravity doesn't work that way

Games:

20,000 leaks other than being an incredibly lame name/idea for a game, is reasonably responsive, unlike Reflex Ridge you don't really have the lag getting in the way.  As the name sorta alludes to, you've got leaks and you need to plug them, how do you do this you ask? Well with your hands, feet, and head. The longer the leak goes unplugged the more water that will fill the tank/sub/bathysphere you're in and you're under a time limit.  It's mindless, it can sometimes not do what you want your avatar to do, this only becomes an issue when you have to plug multiple leaks at once to fix them, if you have any clutter/friends you might want to move them I almost slapped a friend trying to plug a leak when the avatar didn't do what I wanted it to.

Rally Ball is brick out with dodge balls, it's sorta fun, much more so than 20,000 leaks, much like the lag in other games when the balls moving fast you can end up missing the ball, not a huge deal since you take up most of the area anyway so 90% of the time you'll hit the ball without even trying lol you really only swing when you want to put that extra power behind it. 

Kinect Sports:

Much better than Kinect Adventures all around but only got to play bowling and boxing.

Bowling, it simply doesn't beat Wii Sports/Resort/High Velocity Bowling, that said, it's good, it's fun, it's enjoyable with friends and it's responsive.  The main issue with the game it's hard to repeat the action you did to get a strike and sometimes you'll get a totally different response, something that doesn't happen with other motion bowling games, like you want to hit the 1/2 or 1/3 pin to have a better chance to get a strike, one time you'll do a motion that will allow you do to it, try to repeat that motion and for some reason the same basic motion will add spin and you end up only hitting a few pins.  One reason other bowling games top this is the tactile feedback, something in your hands that you're moving and simulating throwing the ball down the lane.

Boxing, the lag creeps in, no where near as bad as Kinect Adventures again, and it doesn't cause problems unless you're trying to quickly switch blocking positions to block a punch.  Punching itself is a lot like Wii Sports boxing, blows to the head, blows to the body, mix up to get around blocking, it's fun, could be better though.

Bottom line:

The Kinect itself has lag issues, you're not going to have a game that is immediately responsive, games like Dance Central seems to mask things a bit better cause of the sort of game it is, but others can't have that luxury.  Not having any other ways input actions IE not having a joystick will limit what types of games can be made severely, mainly meaning games will have to have characters either stationary or on rails.  

Is it all bad?  No, by far it's the best motion camera I've ever used.  Is it for the mass market?  Hell no.  150 dollars is a pretty steep investment for the average person (if they have a 360 already), it requires more room than the average person has, and games just don't have the magic of Wii Sports, or fun of Sports Champions.  

Hopefully I can get the chance to play Dance Central soon cause that seems to be THE game for Kinect and could be really fun.

apearently no game can be played while sitting down,,,is that true?

None of the games I played would be able to since it would require you to kick, move positions, as well as move your hands, so that feature I couldn't test.

good impressions regardless

Is a $150 really that expensive for the masses?

Its cheaper than most iPods, smart phones, and many other gadget yet I see plenty of people walking around with high priced devices. Lets not forget how much people waste on other useless crap.

Maybe a $150 isn't as much as you think to the masses?

lol yes because that's the only reason I listed, between price, room size, and games is what makes it not great for a mass market, it's not like Guitar Hero sold any better by getting more expensive if you want to bring price into things.

Plus if we are to believe the online gamers and websites then just about all Xbox gamers are core gamers as is, so its only a 150 dollars investment for them, for the casual gamers that went for the Wii that's a 300 dollar investment starting out, or the average joe could save 100 dollars and buy a Wii which is popular, his friends have, has games, and doesn't require a lot of space to use.

The average Joe could save $100 but then they wouldn't be getting the hands free gaming that is the main selling point of Kinect.  It's much like in years past why it didn't matter if the 360 was cheaper than the Wii since it wasn't offering the same (unique) experience.

I don't understand your Guitar Hero anology. But if you elaborated I can tell you why its stupid.

What exactly is a core gamer exactly? Someone who doesn't like Wii games? What about people who just play a few game like Halo and CoD? Are they core even if they don't have interest in many game?

People could just get a Wii and save money, but it also depends on what people want to play or experience they are looking for. The Kinect seems great on its own and when people are done with motion games. They can also delve into the the 360's wonderful library that uses a thing called a joystick. Hence, its not like $300 just gets you a machine that plays Kinect games.

The hands free part is the thing that's limiting it and I really wouldn't say unique experiences since most games like Boxing and Bowling simply is trying to be like Wii Sports, while other games like Reflex Ridge in Kinect Adventures is much like the PS2 eye toy games, main one that comes to mind is Antigrav and that game was actually more responsive.

LOL Guitar Hero is one of the best casual games of the past decade, the series didn't grow after World Tour it shrank.  Rock Band vying for the same crowd started the 4 instrument thing and it was fairly expensive too.  Price has a lot to do with if your typical non gamer buys a product, unlike gamers they don't spend hundreds of dollars on games every year.  Also not why you're trying to call others references stupid?  Not really sure what the attitude is going to help you accomplish.

And the whole point to a casual gamer product is they have games they can pick up and play, put down, and play again for 30 minutes to an hour with themselves or with others, they're not likely to sit down and play games that require hours of investment, so using "a thing called a joystick" is sorta pointless to them unless you can think up some exceptional casual Xbox games that use the joystick (again that was more needless attitude that isn't doing anything for a debate other than trying to rile things up, makes the other person mad, you don't get anywhere in trying to convince someone of your point by doing that)
