Back to my original point. I've been waiting for over a year for the 2nd generation. It would be foolish at this point to give up and buy the current one. If I was going to do that then I should have done it long ago. It really has nothing to do with Haswell, which appears to be underwhelming, or even to have the latest and greatest. It has everything to do with my gut telling me for over a year not to get the 1st generation. And I'm well aware that my gut could be wrong, but I've had bad experiences with 1st generation MBPs in 2002 and 2006.
I agree on first generation products in general. But it is over a year and they are working out the kinks, anytime new hardware is used more issues can arise.
I think you are better off buying now as the 1st gen. is matured and they have fixed most issues.
The new hardware changes when first are released in new the new rMBP could have issues that may need to be worked. Maybe not.
All I can say is I got my Apple refurb 13in rMBP in March/April and it is a flawless machine. Whatever needed to be refurb was and the machine and software have had 0 hiccups. There are no lag issues. No screen issues, no overheating etc.
I wish, I could say Apple quality is top-notch but my experience with iMacs, iPods, iPhones and iPads begs to differ despite their high cost, the first unit released in any generation seem to have issues.
I cant say the upgrades wont be worth the wait but just because it will be a 2nd generation does not promise no issues.
What if the PCie SSD interface has issue with intermittent data corruption or something, on some but not all machines. or whatever, I just would not hold my breath that all things will be perfect with an Apple product
I bought my wife 2-3yrs ago a 21in iMac, 8 months in the HDD drive failed. Apple fixed it but they were not helpful with my data issues and how it affected my wife's business. When we bought the machine they never told us about their business services they were harping we should have gotten
I know HDD fail(though never had one die like this one). Apparently Apple was aware of big issues with the drives failing, they eventually recalled them. But we were made to feel like we at fault for the drive dying and not having paid for their extra services. My backups were corrupted because the drive was dying.
I had to beg for the old drive back to see if I could retrieve the data myself as they were not helpful at all.
So my personal experience says buy when you need but do not hold your breath about issues. Just hope they work well. Apple in the past loved their consumers but now that they are so large alot of the excellent CS is lacking IMHO.
