Too bad you stopped using Linux UbuntuGuy
Well this new computer came with Windows 7 and I just realized how much I've been missing...
Thing is, Windows 7 is really great, I think it beats Ubuntu by a lot personally. Though, Debian however...
Also, I have about 8 computers, one ran Windows 2.1, another Win 98, another Win XP, and the three in use are my dad's business comp (running vista), mine (vista), and a generic family one (Win7). Oh, and an Apple II and a Comoddore 64 and 128
Edit: soon to be 9, getting a laptop today/tommorow, and I'll see how it fares with Win7 (I mean, it's a $500 one with an i3 processor, so... It should be rather fast) and if it doesn't, I'm following souvik's advice and loading it with the #! Debian variety.
Edit: spry, it was actually going to be the same as your Samsung R540
however my dad just agreed to go with an i5 version. Still Samsung, since for non-commercial laptops, they are among the best producers.
