Like many other developers today, I am using part of the time Visual Studio 2003 and part of the time Visual Studio 2005 (Whidbey, beta 1). VS2005 is so much user-friendly, more productive, fast and advanced that using VS2003 becomes frustrating experience.
Still we have a lot of clients and projects in various stages of development, which use VS2003 and Framework 1.1. It is impossible (in current version of VS2005) to build solution compatible with FW1.1. I think, this limit will prevent a lot of organizations (especially medium and large) to enter VS2005 beta process and will delay adaptation of new tools (FW 1.1, VS2005, Team System). It is definitely make my life harder :) . The funny thing is that this functionality is pretty easy to add. It can be done through special task in msbuild.
