- Download from MSDN was OK - not as fast as some MS subsites, but faster than others. Certainly acceptable speed.
- The SP installation process seems to take a long time. I did not measure the first two, but the third (on a 1.7mHz Centrino box) took just under 15 minutes.
- The SP installation package is BIG - the network SP iteself (xpsp2.exe) weighs in at 272MB. Running this executable expaands the SP into 332 MB temporary folder on the local hard drive (although these files are deleted after SP2 finishes installation).
- Upgrading from 2149 did not require me to remove the earlier version of the SP before installing th RTM version. The earlier build on my main workstation DID have to be removed before I could install the RTM version.
For planning purposes, if you've done any widescale deployment of interim beta versions of SP2, it probably makes sense to assume you can't upgrade the earlier version. Thus, allow time to deinstall and then reinstall SPs.
For me, the SP installation process has been relatively painless and thus far, I've had no real problems with any of these machines. So far, so good!
