Riccardo & Marek,
Having talked with Steve also and Scott. They never said it would be bug free. To the contrary, in my post about my conversaation with Steve, I mentioned he was straight up about it.

The question becomes what type of bug and whether or not the average user will run into them or not, or will they be deeper bugs. They know that there will be bugs or possibilities of them and is why the o/s is upgradeable.

As far as the time it takes to upgrade. I have some equipment that reads and writes pretty fast and other stuff that slugs. Any equipment I own that follows this sort of procedure for upgrading always comes with the warning..."do not shut off the power during this procedure."

Is this the best scenario for upgrading this or any keyboard? Probably not. Have we all looked at many products and said "if I designed this thing I would have...." I know I have.

A few key things:
1. It is upgradeable if necessary. 2. It is a proven o/s which has been very stable 3. Worst case scenario is, it may have to be sent back to Yamaha to upgrade.

Think about your present equipment do the bugs that it has render it useless? No, usually they are more annoyances than, it quits working.

It is my understanding that for all the PSR 2000 moaning about the non flash o/s that no-one has sent their unit back to Yamaha to upgrade it. They all seem to be still working and making some pretty good music.

My new car (a year old now) has had some bugs in it and has to go back to the dealer from time to time too and it costs alot more than the Tyros does.
