SP1 Installed
The VS08 SP1 install took about an hour to install. At one point it told me about running processes and I told it to retry. If I just ignored, it might have finished quicker.
TFS SP1 was a really quick install. about 5-7 minutes I think.
If you are using Silverlight, you need the updated Silverlight chainer for SP1. That install finished just a second ago. In my case I was brave and did not uninstall the old Silverlight bits. The install did not moan
Overall, quite painless for me- but I now need to actually test it.
