Yeh I tried IE8 Beta 2 for a couple of days. To say that it's a little 'buggy' would be an understatement. Are they sure it's not IE8 Aplha?
New tabs had a fit every time I tried to open one.
Online banking, for me at least, didn't work - told me my browser was not supported.
Some pages loaded very slowly, if they loaded at all, others seemed to load very fast.
Had to switch to 'compatible view' for many sites before I could read them.
SkyUser still looked good tho
Oh well. Back to IE7 and Firefox then
