My poor little TC1100 has developed some pretty weird issues - but I can't say that I am surprised. I've been installing and uninstalling all sorts of software - much of it beta - for the last few months. I've swapped over to the secret tablet for now and will be using that until I get time to rebuild the TC1100. I promise to post a full review once the NDA is lifted.
In the interim I have the secret tablet running Windows XP Tablet Edition 2005, Office 2007 Beta 1 Technical Refresh, IE7 Beta 2, Active Words, Mind Manager Pro and more.
