Time and lack of interest. Don't get me wrong, i would certainly enjoy a lot of games on PS3 or 360, but very few of them stand out as something i really need to have.

I decided my money was better spent on a graphics card instead of another console. Offers a good chunk of the PS3 catalog, most of the 360 catalog and obviously PC exclusives. Perfect match for the Wii.

.....and it runs higher than 640p.

Because I don't have time to play around with other systems or money
I use my DS and wii perfectly. They both between them never run out of games to play. Why buy anthor system when you already have 2 that feed your needs

Expense is the main reason, but to be honest if I had more money I would spend it on more Wii games first.

Neither of the consoles has an interesting enough library for me to consider buying them at their current prices, the X360 barely has 10 games I am interested in, the PS3 probably double that, many of them the odd unique PSN games.

I have zero interest in their multimedia capabilities, and the fact they are HD means nothing to me considering I game on a 13" 'portable' CRT, and on occasion when I transport the console downstairs it's a 27" CRT... both are SD and neither will be replaced until they break. (For my bedroom one I think I would probably go up to 20".... the living room won't fit much bigger than what is currently there, if the screen goes right up to the edges then a 32" might fit (current TV has speakers either side of the screen)

I'm not about to buy one now, when the inevitable slim/natal 360 is coming in a couple of months along with what will likely be a $50.00 cut in price.

I bought a PS3 way back 3 years ago solely for FFXIII and other JRPGs. Square Enix has failed me for the last time!

Thank God Demon's Souls and Valkyria Chronicles fell to my hands, though. Especially the first.

seems mostly its an issue of money. thank god im not broke so I could get all the consoles (except 360, until MS finally deciedes to REALLY fix RROD)

Time and money

Would never have enough time due to college work and plus it iwll be extremely expensive in the long run.

I can not support 2 consoles at the same time.

Games are very expensive and i can only afford 1 system per generation U.U

But i wont deny the PS3 and the X360 are worth it.
