Okay, I decided to do some acid3 tests, took some screenshots to share with you all.
I'll start with Linux, which ran via remote desktop (its hooked up to a TV).... (System: Debian Squeeze x86 / Kernel 2.6.32)
Iceweasel 3.5.8 (Debians version of Firefox)
Google Chrome 5.0.307.11 beta
... Now for windows ...
System: Windows XP SP3
Virtual Machine: Windows XP SP2
IE 8 Standard Mode
IE8 Compatibility Mode
Google Chrome 22.214.171.124
IE6 Running in Virtual Machine (for the lulz)
Oh and for the record, IE was lagging during the tests - I had to give it a little while before it would get to its final score.
There you have it, IE sucks!
