I understand what both sides are saying here, but I bought a mac because I wanted a mac. Yes, the frustration of going into 90% of stores and not being able to find much (if anything) in the way of software is annoying. Yes, macs are more expensive (like caddilacs, bmws, audis, ect...) but you tell me where I can get a clone PC for $2000 with a 17' lcd and a dvd burner that looks so good in my house and takes up so little room. I am a consumer and I don't need many programs, but I sure use iTunes, iMovie, iPhoto, sherlock, appleworks, and iDvd quite a bit. Gaming is lacking, but not horribly. I have my favorte games on my mac. I play CIV3 and the sim games and I run tons of emulator software (for atari, nes, snes, ect.). I Use my iMac for web surfing, e-mail, editing video and to burn cds and dvds and thats about it for right now. I would enjoy a bit more speed, but I could get that with a $100 ram upgrade. I don't think most people are concerned with the Mhz issue as much as you think. I think most people (the average consumer) are just uneducated about macs and what they do, and so don't even bother looking.
By the way, this is my first mac. I had a horrible gateway before. It was horrible.
Anyways.... I am thrilled with my 5 week old 17in LCD iMac, it kicks booty!!!
