I'd hardly call some blown LED's "serious sh*t" since the buttons themselves still operate but it would be annoying. The lockups the one poster spoke of are probably software related, not a hardware issue as he believes. I suspect the lockup issue will be addressed in the 2.0 update although Korg may not mention it in the update notes. The LED's were probably a faulty batch from a supplier and once replaced should last for years and years. The downside is of course the time it takes to have the LED's replaced.
I know all about lockups, my Yamaha 9000 Pro had more than I could count prior to Yamaha releasing a software fix. Even then Yamaha never once admitted there were any issues that caused these problems. At least Korg has acknowledged some users have had issues and asked other PA2X owners to report these problems so that they can make sure they are all remedied. That's better than a manufacturer sweeping it under the rug.
You may not be aware of this but on startup most modern keyboards do a complete diagnostic, adjust the AD/DAC's, and run a jack and audio check. Under normal conditions the user never realizes the system checks itself in this manner but when there are problems, it stands out like sore thumb. My Yamaha 9000 Pro had serious issues when it did the AD/DAC adjustment and often I'd have nothing but noise emit from the instrument, no sound at all, or worse yet extreme distortion and clipping. One might think this was a hardware issue but it was actually a serious software bug that caused these problems. Fortunately Yamaha did address some of these issues but not all the problems were remedied prior to Yamaha discontinuing the instrument.
Any instrument can be prone to failures and one should expect that these things can and do happen. The scope of the problem and how the manufacturer addresses it is shows you the type of service you can expect from that manufacturer in the future.
I've never had a hardware problem with any Korg keyboard I have owned and even with my Oasys Korg was always quick to offer bug fixes to their software. I'd like to have seen more changes to the Oasys software for added features to the sequencer and audio recorder but as far as bug fixes went, Korg couldn't be faulted.
