What he said. Unity will be the death of Ubuntu on the desktop.

I hated it from the first day I saw it - the day that it appeared on my netbook screen. I even started a thread about it. Clearly I'm not alone.
I used Linpus (default OS) when I got my netbooks, then tried Ubuntu 9.04 netbook remix, which was brilliant. Then I upgraded to 9.10 and 10.04, which were getting slowly worse, more resource hungry and uglier (the brown was soooo much better than that hideous purple). After 10.10 (unity),
I'd had enough, and loaded Mint, which was ok for a while, but that also got too resource heavy in later versions, so now I'm on Lubuntu, and love it.
Linux desktop users are generally not shy to ditch a crap OS (or UI), and don't want or need idiot proofing interfering with their power-user features, so its no surprise that they're ditching unity like stink. Maybe that UI can work on TVs (although my HTPC runs Windows 7 Enterprise), but if Ubuntu wants to salvage any of it's early adopters, it better replace unity with something much better. And by "better", I don't mean "more idiot proof".
Edit (and off topic): I googled unity sucks, and
this was the first result. **** man, those comments had cooldrink spraying out my nose more than once. Read it if you have the time.
