I just bought Psychonauts for $2 on steam, I wanted to buy it for a long time on xbox live marketplace, but the price and region restrictions for my country made me bail. 
The thing is, playing on pc sucks, for me at least, the control just doesn't feel snappy enough, even after mapping the xbox 360 controller, and my laptop struggles to run it smoothly at a decent resolution. 
I don't want to play on my desktop PC because of the heat (it's a very hot summer here in Chile) and the noise, and all the hassle that implies setting up my PC: it's hidden behind a web of cables and just has the power and ethernet cables connected, since I just use remote desktop if I need to use it, mainly for long renders on after effects and 3ds max. 
 So, I may just end up circumventing the region lock and finally buy it on the 360, but I haven't made a decision yet.   
Do I buy it on xbox? 
Does it run widescreen on xbox? 
Do I stop bitching and just install it on my desktop PC?

I played it for about an hour yesterday on my PC (with 360 controller). Didn't really run into any problems (aside from not being able to map to the triggers).

I played it on PC in 2005 and it worked great with an Xbox controller. If I didn't know better I'd say I was playing on a high quality console, having also played it on Xbox.
 
Not sure about widescreen on xbox as I didn't have a wide tv at the time. But the PC version correctly supports widescreen (except minor cutscene and HUD stretching)
 
If you feel HAVE to play on 360 to have a good experience, then that's what has to be done. It's a great game that should be played.

You have already bought the game. So,at first give it a try in your PC.

" @crystalskull2: yeah, from what I've read the xbox version does not run in widescreen. I'll give it another shot on the PC.  If it goes on deal of the week on xbox live I'll definitely buy and play it again. "

Xpadder works well for mapping the triggers and right stick. There's a good post on the Steam forums that has all the links etc. "

Is your 360 controller wired? If so you can use the excellently configurable XBCD 360 drivers. If it's wireless, your only other option (aside from MS drivers with a joy-to-key program like xpadder) is to use some wonky Japanese drivers for the wireless USB receiver which are a bitch to switch between.  I used the XBCD drivers on my non 360 controller when I played through it. "

" It's weird, I've heard some reports of proper MS drivers (for the wired version) that treat the right analog stick as axes instead of rotation. If you could just change the config on the fly, a lot of these DirectInput/XInput problems would go away. "
