how much of an issue is it?
A lot depends on what you use your boxer for:
if you use it for activities which only requite a tap once in a while you'll be fine,
if you use it with softare that requires frequent tapping you might be driven crazy.
BTW ... some broken things: (here are the first 2 that come into my mind)
the usb storage function is not working on r197
you can only undeclock and only by hand (applet does not work for cxx0 family)
If my C860 becomes unusable I will be as sick as a parrot. I set it up ages ago and it has been so long that I cannot remember what I did!
Well I would not say it's unstable ... I also have a 5500 and some time ago it was running on an old rom version ... when I played solitare I had a crash ever 4 games on avarage.
On my C860 I've played for hours with quake and I had no crash. Generally I only reboot it when I want to change between the system on MMC and the on on the onboard NAND.
Make a backup and try for yourself so you allways have an easy way back.
