Gee, and when is IE gonna 'catch up' with Firefox's RSS capabilities?
When will Outlook Express 'catch up' with Thunderbird and offer an Address Book whitelist mail rule right out of the box?
Useless questions, IMO.
At the end of the day, the feature sets of the Microsoft and Mozilla products will NEVER be the same, and which you use -- which is 'best' for you -- will always be based upon your preferences and needs. So don't go trying to start a pissing contest over it.
