I always hear such good things about XBox Live... but I stuck with PC due to preference...

But I never realized how far behind console gaming is until this MW2 debacle.

No dedicated servers on most games?  Local hosts (pardon my french) suck!  Laggy (except for the host), with an unfair advantage to the host, and either the game is interrupted or ended when the host quits?  That's awful...
And the player limits are pretty crappy, too. 

And does anyone else see irony in the PC version of MW2 getting lower ratings than the console versions?  It's the same game with (slightly) better graphics and more control options (you can use a controller, or M/KB).  I guess even PC game reviewers have higher standards for gameplay...

The problem with PC is that not everyone who has a PC can play MW2 but everyone with a 360 can play MW2.

The other thing is that while a console game generally just works with no extra messing with the settings, there are endless amounts of things you may or may not have to do to get a PC game to work.

That's usually where the trade off is.

-edit-

And I'm not trying to say consoles or PC's are better, I'm just saying that those reasons along with just less support in general is usually why PC versions score lower.

I play console games too.  I just do most of my online gaming on PC, and never realized there wasn't a similar server browser setup on XBox and Playstation.

I've played a few Wii games online, but people always talk about how awful the Wii online is (friend codes ugh) compared to XBL... but it sounds like XBL isn't much better at all.

It is quick and easy to use, and the vast majority of the games don't have any lag. The system generally works well, but when you sell 7m copies of the game, there might be some issues with over demand, but it will be sorted out

I am sure that dedicated servers will return for the next COD. They only problem is they will come with a subscription model.

I haven't used the PSN as much, but I can tell you that out of the 130 matches of Halo 3 I've played, only 1 has had ANY lag at all, and that was the day that ODST came out and hundreds of thousands of angry teenagers flooded Live. Needless to say that was my only match that day, yuck to a lot of the Live userbase. Do you know how many times I've heard "Nice game dude" pause "too bad you suck!" just before the matchmaking kicks off to go to a new game. Bleh. PSN is just about as good for online multi, haven't noticed much difference.

What tipe of subscritopn model? Casn u xplain how that works?

Just like all the previous CoD games, the PC version doesn't have more control options; you can't play the game with the Xbox 360 controller.

In CoD4 you could lean...

Sure, you buy the game and pay a monthly fee to Activision to play online.  The current retail model doesn't work for games any longer due to rentals and pirates. Moving to a subscription based model would allow the publisher to gain revenue from these people.  It's the Warcraft model for other genres.
