I installed the beta, pre the full IE7 release and discovered I was unable to uninstall or roll back to a previous version without a full reformat. This put me off IE7 for good and although I realise that it was probably my own fault for risking a beta in the first place I was not impressed with the changes or the apparant upgrade.....IE6 for me, if it aint broke dont fix it!!.
I have also used Firefox & Opera but find something always niggles me and I end up back with IE6.
Personal choice I guess Smile
