My experience with Apples has been diabolical. Through work I've had 2 macbook pros, 2 mac pros and an iMac (still to arrive). The mac pros are slow and overpriced. One of them just died (hard disk fail, after 3 years isn't great but it does happen to be fair).
The macbook pros have been shockingly poor. My first macbook pro had a keyboard/mouse failure related to the battery. It also crashed a lot (like at least once a week, BSOD-level crash). The replacement one is only just over a year old, and has been back to Apple twice already, they've replaced almost every component. It recently died a third time (unbootable, or sometimes boots then crashes horribly before/after login). It needs to go back to Apple again. It also had a bad screen - I can't really describe the effect, but washing out of the corners gets close - but it was gravitationally affected. If I left the computer at an angle with the top edge of the screen pointed down, the top edge would be washed out. After half an hour, it would be the bottom edge washed out. Very odd.
So my 2p on this is: don't buy Apples! They are expensive, slow (easily outperformed by any of my home machines which cost 1/4-1/3 of the price), and unreliable, both in terms of crashing and poor consistency of build quality. If you're lucky, you may never have these problems, but I'm not the only person I know who have found Macs to be completely cr@p.
