I'm not a tech guru as many here are.  I really like Unbuntu.  I used the Wubi installer:

http://wubi-installer.org/ to put it on my Windows based Gateway laptop.  This has

only 1gb of ram and Windows boots slow but Unbuntu is as fast as a lion.  The Wubi

method allows you to check it out and decide if its for you.  It can be removed easily

and doesn't seem to damage Windows at all.  In fact when you turn your machine on

its asks what OS you want. 

That said; Unbuntu has issues.  Many wireless setups just don't work.  I've read

because some makers of wireless internal and external cards won't share their

drivers, etc.  with Linux designers.  I found a D-Link that worked so its cool.

Better then Vista, maybe.  Different for sure.  Think about this:  Windows 7 is

out.  At first it was a free download and use for a few months.  Now its $50.00.

Its great from all accounts but compare $50.00 to Ubuntu's price 'free'

Try the Wubi method out for yourself.
