I'm so glad that someone is writing about this issue. It is important to understand that 12.04 and 12.10 both SUCK.<p>Here's why:
Previously I was on 10.04, the best thing that happened to me ever. Boot speed was amazing and shutdown speed was the fastest among the three OS'es I had then (Windows Vista, OSX, Ubuntu 10.04).<p>Then something happened. I purchased the Windows 8 Upgrade edition and I had to partition my drives (because I wanted to) and I thought "you know what? Let me upgrade my Ubuntu, it's been sometime since I upgraded it." I upgraded it to 12.10 and I used it as my only OS before installing Windows 8 (because the setup was corrupted and I had to re-download it).<p>It was a nightmare. Unity is a nightmare. Before using 12.10, I was on 11.x and 12.04. I don't see why they have to thrust Unity onto your face. Everything was really fine before Unity came.<p>Unity is one of the poorest experience one could ever experience on any operating system. I'm not sure if it was inspired from some other OS, but whatever it is, it's a poor implementation and clearly no proper research has gone into designing Unity. For example, switching between open program windows is a nightmare, if you have auto-hide enabled, it just gets worse. If you are a developer, nothing could get even worse than trying to switch between a text editor and a web browser, for instance.<p>Now to the core, the OS itself is painfully slow. Post installation of Windows 8, I compared the boot and shut down times of both the OS'es. I'm not exaggerating here, but Windows 8 shuts down much much quicker than 12.10. The only reason I loved Ubuntu was for its speed, let alone security. Now what Canoncial has done is taken the only reason for me to use Ubuntu and bastardized it as much as they could. Video drivers are another issue. Back on 10.04, I had to manually install Nvidia drivers myself, but it would work well once installed. 12.10 just fucked it up big time. It would automatically try to install something and you will have to spend sleepless nights trying to remove it and install the correct driver only to realize that it wouldn't work either!<p>I know you can bring back Gnome using some terminal commands, but the speed of the OS itself is still slow. Try switching between tabs on Chrome, you'll realize what I mean.<p>Ubuntu's target audience has always been developers and power users first, and everyone else next. With Unity, they're <i>trying</i> to push Ubuntu towards general users, which will be a difficult task. Moving away from your target audience to attract a newer audience is the worst strategy I could ever think of.<p>Hence, here's another Bye-bye from me to Ubuntu. Hello Windows 8! (single boot!).
