I have installed Office 2007 in my eo v7110 and I installed recently the B2TR. I completely agree with Warner Crocker at GottaBeMobile, after this release Office 2007 is running a lot faster than it's previous release and than Office 2003. I like the changes in Outlook but at the same time I have ran into some problems. Now two of my Outlook "must have" add-ins are not working any more: TEO and Trend Micro Anti-Spam Pilot. These two add-ins were working in previous version and now they are disabled and no matter what I do I can't enable them back. I have contacted both companies but I have not received yet any reply with a solution for this issue.
You can find a long list of other issues and in some case solutions here.
