I just installed Ubuntu Raring Ringtail on my HP Sleekbook and I am loving it. Battery life went from 2 hours with Windows 8 up to 5.5 while using Ubuntu 13.04 and that’s with screen brightness a little over halfway full so that is very good. I hate Windows 8 because it has a lot of annoying features such as when I click the shut down button, it doesn’t shutdown but rather logs off. Windows 8 has lot’s of Apple copycat features. Too much for me to deal with. I am sticking with Linux Ubuntu. The good thing about Linux is that it is less prone to Malware and viruses than Windows is.
