Early adopters will always be the ones to have the most issues. I always wait a bit and read the results after a release- software or hardware, and then when it seems most of the stuff is worked out, usually in a couple months, I take the plunge.
As far as Apple's product quality, I would say they are still the best even if they appear to be going through a rough patch since Steve's departure. I do believe that the recent restructuring will make a very positive difference and bring back what we love about Apple. If I were you, I wouldn't worry too much about buying an Apple product. Even if you don't like your experience and decide to go back, the resale value alone is worth trying it out. Try reselling a Windows machine for half of what you bought it for a few months out of the box, and you will see what I mean.
Good luck to you!
