the linux desktop problem will get fixed[i know that much] the problem is we are facing a war with one of the most dirt douches of the planet[microsoft] since somehow they know that a beatiful linux experience out of the box can seriously harm their monopoly[see the mobile sector for example], the problem is this famous draconian deals to convert every OEM/vendor in a linux enemy[at least the big ones] making the road very hard but many skilled ppl everyday find ways around it and once linux can operate well enough on this faulty hardware and we find a way to have access to OEM i think linux will sky rocket[and microsoft would go 100% patent trolling tho :( ] but patience is a most here.
I can confirm power regression is HUGE on my AMD Thinkpad laptop at least on Arch 3.5.3 kernel, previous 3.4.9 was not exemplary, too (3.4.7 was better).
And only Ubuntu with kernel 3.2 could get me 5-5.5 hours - closer to windows, under which i get 7 hours, +- 2-3 hours, depending on usage. Which led me to think that from a user point of view - windows power management is more "scalable" and "adjustable". On windows you can save extremely even when battery is almost over.
This situation is completely awful, and I agree with
Which, of course doesn't mean i will switch to windows or Ubuntu because of that. It's just the way it is...
