Jepp,
If it's any comfort I have now applied four software updates to my 196 since I bought it. It's a very straightforward process and it has always worked flawlessly.
The unit came with version 2.01 of the software and did suffer a total lock-up while in 'Land' mode once. It's now on version 2.06 and I have had no further problems.
The little logbook program you can download to collect flight details from the 196 is quite handy too.
