I've just upgraded my old laptop OS (it's a Toshiba Satellite T130, and must be about 5 years old). Previously, I had been running Elementary OS Luna which I found pretty impressive. It had a couple of niggles ... for example the file manager app always seemed to take ages to load. Now that the new version, Freya has come out, I decided to try it. I went for a complete wipe and reinstall.
I am quite pleased with the upgrade. The slow file manager startup time has even gone away, and the whole OS seems even more polished. However, I have had a problem with the pointer getting corrupted if I did drag and drop, which was annoying, I am currently trying this fix, hopefully that will make it go away. Anyway, I celebrated a successful reinstall by going off to the Nasa JPL Wallpapers site and grabbing myself a nice background, so here's a screenshot:
I think that it's still the most visually appealing Linux I have tried and I'm quite happy that I've upgraded to the latest version. It runs nice and fast on my old laptop, and it's nice to have something that looks good without eating all your CPU cycles.
