I like performance and apparently high-end Crays are the cheapest from performance per dollar point of view. Problem is - that high end is way too expensive. Comparing to Dell implies Dell is the cheapest, but at least in the UK this is not the case. Locally assembled computers are very popular because they are very cheap and should things go wrong you can pop into your local store where owner depends on your business rather than wait in queue with Dell.
The author of the article also fails to appreciate that home users are more likely to get Office CD from friend or download it from P2P network rather than pay any meaningful amount for it.
This is the primary advantage of PCs - cheap hardware and cheap or near free software. Who cares if Macs are cheaper if I can't easily run software that I've been running for the last 10 years? And new games, and new this and that - Macs are simply a non-starter to most people.
If you like Macs and they fit you then fair play, but I feel sorry for some of them who were duped into buying Macs by salesmen and ads like that "G4 (5?) is faster than Pentium 4" that failed to highlight simple things that matters to people like inability to run their newest game.
I would if there was not good competition offering free browsers. IE (and now Firefox) are the most commonly used applications on my PC - one might say I would not be able to live without a good browser and certainly would pay reasonably amount for IE6 rather than use NN4. Luckily I don't have to as I switched to Firefox full time, but in principle browser is such a widely used application that I think it beats Office in terms of usage and is next to Windows itself.
I will be building a few servers soon and I wonder what would it have cost if I had to go Mac route:
1) AMD 2.5Ghz CPU (+mobo+box)
2) 4 x 250Gb hard drives (1TB in total)
3) 2Gb of RAM
My current understanding that I will fit it all under ~ £800 (GBP) or $1,400 (USD).
