Ugh! - I wish IE9 rendered like IE8 !!
I can't co-exist with the IE9 ClearType/Sub-Pixel rendering... it is completely unreadable rendering for me, no matter what I do with ClearType adjustments, and no matter what hardware I use (including my rather expensive large IPS monitors).
All other browsers are perfectly clear, and even IE9+ChomeFrame is excellent... but native IE9 simply sucks as far as I'm concerned.
The only way I can live with IE9 is to make ChromeFrame the default rendering engine (a reg key) which rather begs the question of why bother with IE.
