SP1a removes MSVM, so java applets won't run unless you reinstall VM or that coffee cup sun java. I don't like sun's java, I don't like the message java applet opening, and I hate the coffee cup in my system tray. However, MSVM is no longer supported so if you can live with it use sun. If you can't deal with sun, (I can't) there are ways to get MSVM. You can download SP1 and extract VM and install it, or you can just use SP1.
You can find VM on some shady sites, but I don't recommend that. It is all in what you prefer, I prefer to run SP1.
