I agree the money arguement is pointless as each person must decide what is the better value and not dollar amount. Being a long time PC Gamer I'm shifting more towards Xbox 360. I recently sold my 8800GTS 640Mb, Sold by E6750 comob, returned to my used 1900XT/opteron 939 combo, and invested that amount in games for the xbox.
The major reason for "me" that I'm more of a multiplayer person and enjoy playing with friends and family. Having a family and responsibilities of my own, my time is limited to play. I started noticing more, and more, of the new releases requiring steaper system specs "DX10/Vista which was bogus for those titles" and "Pixel Shader 3.0". The pixel shader 3.0 was the bigger blow as many of my friends were in the ATI camp with X800 class cards, which I still consider good cards. They were also running older AGP, Memory (512MB or DDR), and/or lower class CPU for today's standards. So really they were looking at at total upgrade.
So for them the pc's are still perfect for windows/internet/application use but not for the latest PC releases. So more and more of my friends/family were dropping off due to H/W requirements.
All of us having gone through several upgrade cycles among the years, they decided to jump on the console route so they wouldn't need to upgrade the PC as much. So the beginning of the year I was the sole xbox 360 user, now out of 10 of us 9 have xbox 360s.
Were actually playing a little more as it's nice to just jump on, seeing someone on, know that games are at the same revisions (ie not waiting for >500MB Patches), not tweaking for VOIP (for the technically challenged friends), and just joing a game really quick.
What also bugged me was the lack of co-op games for the PC. The console provides that via the same console (minor) but allows internet plays as well (major. 4 player co-op on Halo 3 was great). On the pc specifically where most of my multiplayer gaming took place, there's only so many times you can have a 30 kills to 2 death ratio during a deathmatch game and get takers on another round.
So for me I'm falling back on the PC upgrading and game purchasing, and going more towards Xbox.
As far as console games, I agree the 60$ price tag is steap. However, I'm actually buying more used games in the the 15$ (call of duty 2 for example), and <25$ (Oblivion for example). Problem in the past with buying used PC games you didn't know if the online key would work (ie in use) so I was always reluctant going that route for PCs.
So there's my take. I don't knock anyone for choosing either option.
