I got the 4.5 developer edition for free (legitimately! through a www.osnews.com
/ lindows.com promotion)
Got to say I'm not impressed. Didn't like my sound card (AC-97 standard motherboard chip that even win98 picked up).
Takes nearly 5 minutes to boot up.
Doesn't like playing movies in full screen.
I didn't try installing any windows stuff because they have toned down the hype about windows compatibility.
The screen output looks fairly bad on tv screens, worse than i expected.
Did you have any joy with it?
