well for the matter of general discussion whether the problem is solved ,i prefer GNOME , because i feel its light weight then the other environments .
Two things:
-GNOME isn't a distro, it's a desktop environment (which you somewhat alluded too
-It's not the lightest: the lightest is probably LXDE or XFCE. GNOME and KDE are the two heaviest desktop environments in common use.
and beauty of linux variants is that , they come with a live CD you can try it out with some options and select the best one whichever suits you :]
Yeah, it's great for maintenance as well

I have Linux mint on my dell 1705 laptop with Windows XP pro.
It was so easy to install. I like it. Performance is not an issue for me. Ease of use is what I need. No trouble finding my wireless home LAN. Works great. Some others I tried did do not play well with lmy laptop.
Mint 7 hardly found anything on my laptop, and it's network connection kept dropping off when I finally got it working. Mint 10 however had absolutely no issues at all, and it has become my main OS on my laptop.
