Be patient... be very patient. Oh, also uninstall web application projects
My experience in installing VSTS SP1 beta is be patient. Be very patient. I found on every machine in which I performed the install it consumed massive amounts of ram, all of the cpu resources it could grab and took an inordinately long time.
One significant recommendation is that if you have installed web application projects for Visual Studio you need to uninstall it before performing the SP1 beta install or else you will wait patiently to only then be told that you must do this action. Not fun. Also good to know is that you can leave the Web Application Deployment module installed without problem. I tried it with it installed to take one for the team if it didn't work so I could state definitively that it must be uninstalled or not. In short, uninstall Web Application Projects addin but you can leave installed Web Deployment Projects addin.
When you first start the SP1 beta install it may seem like you didn't get it started but check your taskmgr. It's there. Again be patient. I found it took a long time before it showed me a screen that gave the indication it was doing anything at all.
I thought initially it the resource usages was perhaps related to my virtual machines or related to Vista on which I was also installing the SP1 but no it became the resource hog the same on my notebook running XP SP2. The install to Vista I have been in desperate need of so that I can complete some new screen captures for the book. I was planning on completing those before lunch today but I found my Vista install lacking in a number of areas I had forgotten about. Areas such as the Visual Studio SDK, snagit 8.0 (yet another license), the new VM additions from the Virtual Server RC 2 SP1 beta (which by the way helped the Vista performance tremendously or else had the placebo affect and I think it helped).
It looks as if my install to Vista of all the 'stuff' I needed is at last almost complete now I can get back to edits and writing.
