I just upgraded my version of Ubuntu from 9.10 to 10.4 and all I have to say is,.. “flawless.”
I have a couple of specific hardware and software configurations on my system and I was prepared to go through the troubles of having to recompile software and tinker with the operating system files until everything worked again. To my surprise, I did not have to touch anything on my system after the upgrade!
The installation was quite perfect, everything is up and running and for some reason, the system is just faster at performing tasks.
If you hate MS Windows, and/or finding your system sluggish and slow, you might want to back your hard drive up and use Ubuntu 10.4.
