Of course, going back to Windows after 3+ years on OSX is no option, so I looked into Ubuntu. I use Ubuntu on a machine at work and have been very impressed--we've certainly come a long ways since the dark days of Slackware `96! I am enough of a "power user" that I could weather the switch just fine; really the only thing I would miss is iTunes since I have two iPods.
Anyways, I started Googling around on the topic of "hp envy 14 +ubuntu". And that's when I was instantly transported back fifteen years to the days, weeks, months I spent tinkering with past laptops in order to get everything working on them under Linux. I had all but forgotten about 30-page hardware HOWTOs on getting Linux to work with your specific laptop; the 20% battery penalty you pay because pm never quite works; the inability of some things, usually network and sound cards, to wake from sleep; the lack of hibernate; buggy graphics drivers; etc. etc. etc.
I am aware that the situation has improved considerably since then, but problems still remain. I just don't have the time like I did in my teens and early 20s. Or rather, my time is worth considerably more now--I'm happy to pay the Apple tax if it means I don't have to deal with this shit.
That said, if some major HW manufacturer ever came out with a completely supported laptop with Ubuntu preloaded, working power management, graphics drivers that do what they are supposed to, etc., I would totally bite. (I am aware the some, e.g. Dell, have done so, but when I see warnings like http://en.community.dell.com/support-forums/laptop/f/3518/p/... it's evident that they half-assed it. What I'm after is a full-assing.)
