Ive been testing Ubuntu Unity for about a month on my Acer Nettop.
Other than a few bugs when it was in its alpha state,It has run fairly well with minimal hickups.
The Unity Interface does take some getting used to,Like having to highlight a window to get to its settings,Which normally would be on each window thats open,With Unity its on the taskbar.
I dont see this as simpler than having it on the open window,It doesnt really save all that much space.
At first this annoyed me,But now im used to it.
In the Alpha version you do have the choice to use the older gnome style desktop,When logging in you can choose between Ubuntu Classic and Ubuntu Classic no effects. Or something like that.
Ill admit to liking the Unity interface now.
Im hoping for a fix for Dropbox,It can be installed,But theres no taskbar icon,And any of the online tricks havent worked for me,It still works,And im sure in time it will work itself out.
I dont have many miles on Mac systems,But id have to agree with the many similarities.
Im not sure if this is a good thing or a bad thing,I thought the whole reason for this type of interface was for touch screens.Im thinking an Ubuntu Tablet would be hot,And theres already a few youtube videos out there showing how well it works on certain tablets.
I like to think its a step in the rite direction,But only time will tell.
