My rule of thumb is to avoid IE whenever possible. Popups, malware, security exploits, and an endless list of problems. (Bad standards support, such as sucky CSS and no PNG support, etc) Hasn't even been updated in years.
Almost every browser EXCEPT IE has popup blocking built in. And TABS!! got to have Tabs.
For windows, there Mozilla, Firefox and Opera.
Mac users can also add Safari and Omniweb to the mix.
I like Omniweb. =)
