As with previous versions of linux, the thing that trips me up is drivers. I know that the fault lies with many mainstream hardware makers who have still not caught on with Linux, and don't provide driver support. Anyways, installed Ubuntu on my acer laptop, couldn't get wifi to work. Once I solved the wifi driver problem, I found that the ACER laptop has a special driver needed to manage the buttons upfront, without which the wifi device is off. Got too deep for me to fix (required creating make file for your system and compling a driver), in a small amount of time so no Ubuntu on the laptop. I do have it installed on a dell desktop without any problems for those times I need to run some linux apps, but I don't spend as much time on the desktop as I do on the laptop. So instead of two thumbs up, I would give it one thumbs up instead.
