A slow experience installing VS2010 SP1, but worth it in the end

I got round to installing Visual Studio 2010 SP1 on my laptop last night; well I started last night via the Web Platform Installer method. It downloaded the bits fast but sat for ages on the first step, installing the actual service pack. There was no obvious activity on the CPU or disk. In the end I gave waiting and went to bed. I was pleased to see it was finished this morning.

So the tip here is be patient, applying this service pack is a job you start on your desktop before you go home, not when you come into the office.

So what is the biggest benefit thus far?

I can easily use IIS Express from with Visual Studio, so no more having to run Visual Studio as administrator to us my local IIS Server for development.
