I've been running IE8 beta 1, just upgraded to beta 2 and I noticed something I don't know if I like - "Suggested Sites". I like my suggested sites to come from people I know or based on a search, but anyway, here's what you're hit with after install.
Then there's the usual "let us setup everything for microsoft's search/maps/blogs/etc" -- no thanks and wasn't unexpected. What did irritate me was after install, "Suggested Sites" blinks. Maybe I'm being picky, but if I say "no, don't turn on" that doesn't mean "hey, remind me about this right away". Egh.
There's some slight color differences, thats cool, always nice to re-skin, and I noticed something ... maybe I wasn't paying attention which is very possible, but I see a web testing thing now in IE (maybe it was part of the vstudio 2k8 Sp1?)
Cool. Otherwise, well, my blog works still minus a few miss placements and another noteworthy thing is the "Emulate IE7" is gone and now its "Compatibilty View" under tools as well as "Safety" is now in the top right with the all well-known "InPrivate" browsing ...also known as something else. I'm not really noticing a lot of speed difference right off but again, I could be wrong.
