Last week I was at the SAP summit at Bangalore. A lot of wonderful sessions on architectural topics. My favorites were the one on Security and on Asynchrounous workflow. There was also a very interesting session by Colin Png on the future directions of .NET and Microsoft.
Also there was demo of a prototype of Tablet PC. A really interesting and cool technology, with lot of cool features like Digital ink etc. You can find more information on this at Tablet PC home page. There is also a cool animated picture that shows you how the tablet PC is going to look like and lots of interesting infromation.
