Looks fine so far. Oddly it would not complete the download in IE7 after three tries. It just hung at the 1 second to go and verifying. It came down perfectly in Google Chrome.
The only tweak I had was to update my Windows Live sign in plug in and all was well. This site (PCA) was flaky in 8 so I am running it in Compatibility Mode which is easily done from an icon to the right of the address bar.
I cannot find any UK based sites with Web slices but I have one running from EBay.com to check them out. It's necessary to get the add ons to make some of the features work. So far 8 seems faster than 7.
It should not be a problem.I suppose you would not want to take a backward step to IE7 or IE6.There is always other browsers that you can use if you get any problems.Maybe they should have made it plain for anyone downloading the new version that you could not then go back to IE7.Mind you I use IE7 and cannot go back to IE6 so the same difference.
Took the plunge.I still find it slow compared to Firefox.Speed wise have found no difference between IE7 and IE8 but that might just be something to do with the settings on my computer.Text slightly smaller than IE7 and if you set text to larger then its to large.No problems downloading and running it.Cant get the Favorite Icon off the bottom of the Toolbar so the Toolbar is a bit thicker than I like.Apart from that I have found no other problems.But the day is young.
