I too have IE7. there is no need to fear upgrading anymore,assuming you were worried. There were problems when it first came out I think. I never use IE7 much though. Try maxthon 2.It has many great features. you do need to have IE installed though..Flock is also nice--it you can use the web developer toolbar and some other FF extensions and is constantly being upgraded..
FF is better though--I used to not lke it as much because it was incredibly slow to load and was even slowe while browsing but all that has changed with FF3
