Looking to upgrade to mac pro this year, but playing the waiting game again. Too many times I got screwed by Apple, buying just before a new hardware or OS release. The result is, I hang on to my macs for a long time, due partly to the Apple premium price. Not sure if their model works better than offering a more competitive price and having people buy/upgrade more frequently.
I think determining whether their model works "better" or not depends on whose perspective. Honestly, I feel that as an end-user of Apple's products, I'm really getting a better value for my computer than with comparable PCs.
A lot of people I know with PCs (especially notebooks) end up dropping money on a new computer every couple years. Who knows exactly why, but their computers just stop working right at about the three year mark.
Apple computers, though, last
forever. My dad was using a G3 iMac right up until he died last year. I know there are professionals out there still running G5s of some kind probably even a few on G4 PowerMacs.
I am currently on a five year old G4 iBookancient by most computing standards, but I've never ever had any major problem (ie. an issue that lasts more than a day or slowdown that affects anything but the most intensive tasks). If I weren't receiving a new computer as a graduation gift, I'd expect that I could make this notebook last another 2-3 years at
least, especially if I upped the ram from 512 mb to 1.25 gb and got a new battery (probably $80-100 upgrade in total). That'd make it only about $1250 or $1300 total that I've spent on a computer that has lasted me a hypothetical 7-8 years. If I were buying a new PC notebook every 2-3 years, even at the low end of the price spectrum (which doesn't even take into account all the other great stuff about macssoftware, esp.), I'm way over my iBook investment.
Then again, Apple does charge a premium when it comes to hardware, so they likely have better profit margins than most PC manufacturers. I suppose in the end, it is win-win for everyone.
