Today I downloaded Ubuntu 12.10 for kicks. I installed it on another laptop I have thats an older machine but does perform some things better than my primary laptop.
I installed it on that laptop and its slow as mud. Really I think Ubuntu is going backwards in creating a speedy environment for different configurations. Eventually many of us who have older systems will have to get machines that are more up-to-date and can handle the processes that new software demands. There are several things I didn’t like about Ubuntu 12.10 including not being able to install proprietary drivers out of the box and it seems to be a memory hog too.
So, for me I will stick with Linux Mint 13 which is running well and has provided me a great desktop environment in MATE. I just hope they will keep the bloat to a minimum.
