I have been using Ubuntu as a software developer for the past several years. I have been extremely disappointed with the most recent release of Ubuntu, 9.10, as it has been extremely buggy and seems like a step backwards to me. The conclusion of this review http://www.tomshardware.com/reviews/ubuntu-karmic-koala,2484-13.html also expresses a lot of my thoughts about Ubuntu 9.10. I had so many problems in using 9.10, that did NOT exist in 9.04, that I switched one of the two computers I use at work to Windows 7, for stability (yes, these are crazy days). Do you have any plans to increase quality control in Ubuntu, even if it comes at the cost of delaying the every six month release schedule?
