Ask HN: Moving to Linux full time

I've been a long time (on and off) Linux user but I neve managed to become a full time user. Recently at work I have started using OSX on a beautiful iMac, this has made me realise that I don't need to be dependant on Windows anymore.

The thing is, I don't like OSX. I really want to go back to Linux and stay there this time.

I do see a couple of problems that I don't have to get around though.

1) Using and iMac and MacBookPro has made me really enjoy high resolution displays. By high resolution I mean a nice compact UI where the borders are un-intrusive and the fonts aren't too big.

2) I love Eclipse on OSX and Windows, it's nice and compact and visually pleasing to use. On all distros of Linux that I've used, Eclipse if very chunky, bulky and generally ugly, this makes it very tough to use day to day.

I really want to get Ubuntu (or something with great community support) running on a fairly standard Samsung laptop but the two issues (above) are really putting me off.

Any ideas?
