Obviously none of them are perfect so whats 1 thing you would like them to change/fix.

Wii - Friend Codes. Next generation im certain they'll be gone though.

PS3 - Constant firmware upgrades. I wouldnt want to have to keep updating like what they do with the PSP it gets really annoying.

360 - Xbox live. Main reason I wont buy a 360. I refuse to pay for online.

PS3- I guess install times, nothing else really

Wii- Lack of SMRPG and several other VC games that I'd like to relive

360- Don't own one

^
Even if you dont own one from what you know you can still give an opion of what you like them to change.

I dont own a PS3 but owned a PSP so now how annoying it is.

Wii - I want more/better Wii games.

PS3 - I want more/better PS3 games.

360 - I want more/better 360 games.

360 - Noise, oh dear god noise!

PS3 - Installing stuff

PS3- Price

360- Risk of RRoD

Wii- Bleh online

Wii - Needs more internal memory, or access to playing games from the SD card

Xbox - Hardware needs to be reliable, I'm on my third console.

PS3 - The problem is I don't own one 8). Sony needs to give me one for free. (seriously, I can't speak on the PS3, since I don't have personal experience with it)

PS3 - installing stuff

Wii - friend codes and online in general for some games

360 - don't know enough to make a good judgement.

Wii- controls i cant stand them. really makes me NEVER want to by a game for this system. online sucks, graphics are not at LEAST in HD.

360- loud, broke on me 3 times, Xboxlive fees, D-pad sucks

ps3-no custom sound tracks in all games, cant hook up my zune to it lol, R2 and L2 buttons suck i cant stand them.

360 - the quality of the hardware. (aka noise, RROD etc)

PS3 - the lack of fully developed hardware .(aka blu-ry speed, and the CPU)

Wii - More up to date hardware. (I'd just like sub HD with HDMI)

Games more come down to what programs with most of the devs
