Hmmm let's compare:
PC Gaming+ Is a Windows capable computer: web browsing, typing, able to use mods, able to make mods, VoIP, IM
- Is a Windows capable computer: system maintenance, performance is wild, crashes, drivers problems, glitches, bugs, Steam, etc. One needs to sit down at desk, connect to plasma (burn-in!) TV, or deal with slow laptop GPU/ short battery life.
+ Exclusive PC games
- Exclusive console games (Halo 2 counts here, that Vista port is nothing worth playing)
+ Mouse is excellent for FPS games
- EXPENSIVE!!! (If you want a good experience. Budget machines that cost more than a Xbox 360 means 800x600, low settings, and lag - not my idea of a good time).
- Free online play
+ Games are capable of the best graphics
if you have a very fast machine two years after a new console generation is released. A Core 2 Duo E6600, 2GB of DDR2-800, and a 8600GT trounces the Xbox 360 in performance now (1280x720, 4xAA, etc)
Xbox 360+ Runs only games, that means very few technical difficulties and all your computing
+ Simple
- Loading times are like that of a low-end PC
- Pay to play online
- $60 dollar games that get their price lowered slower than PC games
- Controllers. Hate them or love them, I still think $1500 is worth the lack of a mouse controls and letter keys. I heard UT3 will support them though.
+ Your machine is guaranteed to last 5 years, none of this "Shader Model 3 support was not detected" crap.
+ Price. $350 and some accessories are still a whole lot cheaper than a comparable computer plus the cost of upgrades. In order to be able to play the latest games enjoyably for 5 years, it's about $1500 up front, and then maybe two $200 upgrades down the line. Computers use more power as well.
+ Exclusive console games
I have a 720p/1080i capable HDTV. The expenses of being a PC gamer are completely out of control, mainly due to this graphics over gameplay rat race (Doom 3 anyone?)
