Wow, and I thought *I* was being brash. This debate is heating up!

WARNING: RAMBLING HERE
For the record, the only thing I can think of that is relevant right now is, what is the monthly cost of your gaming experience?
Be it mobile, handheld, console, web, PC, Mac, Windows-on-Mac.
Let's factor in what is the monthly cost of your gaming experience involving iD software? I don't play QuakeWars, don't like the Quake4/Doom3 engine, so for me, iD and Carmack is irrelevant now.
Fair enough I played Quake4 one or two years ago. Was okay, but not great.
According to Wikipedia Carmack's signature mobile game was 2005's "Doom RPG".

Indeed the PC games I mentioned I like are personal preference. Nonetheless it is highly likely for racing games on PC, Windows-On-Mac, [hopefully soon] Mac(Cider), NeedForSpeed: ProStreet is definitely a big, big, big title.
Given my PC specs below (in my signature) I can play ProStreet on MAX settings at 1024x768, the icing on the cake is I can run 8x AntiAliasing. Visuals are crisp yet smooth, gently glowing, yet with hard shiny damage effects, nice smoke and crashes and high-speed racing, etc.
What is the reasonable equivalent of Xbox360, PS3 resolution? About 1280x720 progressive, for the most part. 1080i fudging not counted.
Take an iMac 24", MacBookPro, 1280x720 resolution, and you can play smooth and nice most PC games for the next THREE YEARS. Of course, each year with new games released that year you reduce your game detail settings.
As Solipism says. How much do you save *each* year by using a MacBookPro or iMac24"? By not having to build, setup, maintain and run a separate gaming PC or console? An interesting point for reflection.
Mac, Windows-On Mac gaming with MacBookPro. 1280x720 resolution 2x to 8x AntiAliasing:
2008: Runs all the latest games at 85% of MAX detail settings
2009: Runs all the latest games at 65% of MAX detail settings
2010: Runs all the latest games at 35% of MAX detail settings
If you think of a 2010 game at 35% of that-then-MAX detail settings,
combined with a lot of dual-core gaming CPU optimisations,
Even a 2008 MacBookPro at 2010 wouldn't be too bad.
Compress your Mac purchase cycle to 2 years, say 2008,2009,
new one start of 2010, and the MacBookPro as an all-round
Windows, Mac, Gaming machine, is really not that bad.
Monthly expense for 15" 2.6ghz over 24months (excluding software costs)
