Microsoft has released a patch that appears to help the sluggishness people have been seeing from Outlook 2007. I installed it but I have to ask if Outlook is really relevant any more. We're headed to an all online world but we're not quite there yet. Even so, with all the products available that allow syncing Google calendar to your PIM do we really need Outlook any more? Thunderbird is so much better than Outlook at handling IMAP mail accounts it's not even funny and who out there isn't actively using or looking to use an all online contact database?
So I ask you again. Is Outlook still relevant?
