I need some of you guys that use Ubuntu to help me about some things..
Should I install it?
Don't comment about games, I don't play any.
When I install it, does it overwrite my whole hard disk or does it keep my current files?
Is it faster than Windows?
I have wireless connection, so do I lose that option when installing Ubuntu?
What browser is given in Ubuntu?
Is there an Ubuntu market from where I download applications?
With no arguments, that sounds like some solid advice.
Imo you should give Ubuntu a shot, if you don't like Gnome try KDE, lots of Windows users prefer it 'cause of the eye candy, I personally recommend Xfce because it just feels snappier and more responsive than the pimped out Gnome & KDE but at the same time it isn't as bare as lxde or something even more extreme
