Isn't the top-end Wersi keyboard based on Win98?

Whilst I agree that in general the PC is not that reliable, the usual reason is down to driver and software incompatabilities; for example graphics card manufacturers test their stuff on their own "reference platform" and so do the sound card makers but the two are probably not the same!)(so maybe we should all buy Creative Labs Sound and Graphics cards only?!?!?). In writing drivers for this synth the situation is much more controlled; all the hardware is known and not likely to change. Therefore it is feasible that they have found and fixed the gotcha's. This system should be more reliable than a standard PC.

You can make an analogy with Mac's. The Mac is usually more reliable that the PC because Apple control the hardware much more tightly and so there are less variables to worry about.

And folks, lets not use this post to fire up a "PC" versus "Mac" argument! They are different and thus have strengths and weaknessess that therefore appeal to differnt people and applications!
