Ubuntu has quickly achieved mass attention, it was also #1 distribution for a long time. It has done some great work like ship-it to promote Linux. But I am really disappointed with the current trend. The current release is a mixed bag, but is completely unacceptable in terms of Ubuntu's glorious past.
Installer bugs are a strict NO, for any software. Right now, Ubuntu needs to only focus on "Bug-free, efficient installer". No software can beat the competition if the installer is buggy. Also Ubuntu should not limit the options given to open source enthusiast.
