I really don't care for most open-source software. I find it to be:
1) always in a state of development
2) poorly documented
3) difficult to find support for unique problems.
I tried ubuntu out once. The OS loaded ok, but I could not get my wireless NIC to function. I spent days trying to track down a solution. The advice I got on the ubuntu forms generally didn't help. The only one that did help was a guy suggesting figuring out which check was in the USB stick, finding the source code and manually compiling a driver myself. No thanks. Best quote I read on Limux was 'Linux is only free if you don't value your time'
In general, I like my android phone (Samsung Galaxy). But the phone isn't even a year old and I think three versions of android have been released since (I believe it runs 2.2). That's ridiculous. Linux releases are the same way. It also seems to restart every once in a while for no reason at all. My brother put it best, he said that when I got it I would love it because it was so much better than anything I had ever had before (blackberry and then non-smart phones before that), but slowly the problems with android would bug me more and more.
I'm still not willing to switch to apple due to their draconian policies, but if Google managed this thing better, they'd have a much better product.
