MSFT's stock is going nowhere.
Sony is crazy about thinking people actually spending like $600 on the PS3.
Nintendo's market share is lower with every generation of console, although I think they have the best approach with the new generation (360, ps3, wii).
Personally, I wouldn't buy any of their stocks. Look for a good company who's stocks might actually go up more than like $1 in the coming year.
Microsoft is the safe bet if you want to lose money, or have a stock that does absolutly nothing. http://www.google.com/finance?q=MSFT
Check out the trend from 2002 on. Down or flat.
I have had MSFT stock for a few years now, hoping that it will get up somewhere close to where I bought it so I can unload it, but it hasn't even gotten close. Bought at like $78, then it split and is at like $23 (thats about 46 per original share i bought, down $20).
