Linux on a PC, especially Mint. I tried to get my wireless card working in that for over 6 hours and finally gave up. When I tried Ubuntu, I did have it working after about 2 hours of trying but I just don’t like the OS at all. Linux just does not like the Broadcom 4318 card. Android on my tablet, on the other hand, works very well and I like it. I still say though that it has evolved so far from it’s roots that it can’t be called Linux any more.
