Like the others, I ditched IE a long time ago although I do have the latest version installed.
Use the browser that suits you best............ outside IE, no one browser is "the best".
I like Opera, mostly for the "Wand" facility, a very good and very secure password manager. It is also fast, very secure and has a very small footprint as far as resources are concerned.
I only have one problem with Opera and that is with Hotmail. When it was MSN Hotmail, no problem but now that it is Windows Live Hotmail, I cannot open my mails.......log-in ok, see my mails sitting there, but cannot open them. This is a universal problem, as a quick read through the Opera forum will testify.
Microsoft are on record as having stated that it was their intention that Hotmail will now be accessed through only IE, Firefox or Safari.
There is some technology in there blocking other browser ( packet sniffing..........is that right ? )
TD got round that problem..........scrubbed Hotmail and moved to Yahoo mail which works perfectly in Opera.
