i agree with alot of which i've seen about linux. I ran ubuntu for awhile before i simply removed it due to my familiarity with windows. I haven't had a linux os on my pc due to hardware restraints(hard drive specifically) . I really enjoy the clean interface that linux shells(Ubuntu, fedora etc) all are capable of. they install and remove much cleaner then windows, after my third install of windows xp, i've noticed a degrade in performance and some files left over from previous installs. bottom line is, windows in any form is a greedy marketted base os that people are familiar with. you ask the average person what they use their pcs for and what is it? internet, banking, writing, pictures. ubuntu in all of its baby fashion is perfect for most average users, but windows 'markets' on the idea of a glossier, fresher 'cleaner' look with vista etc. besides, your not going to get the same security from linux unless you run vista ultimate as well.
