I just recently updated to SP2 RC2 and I must say that everything is working perfectly. No problems whatsoever. From what I've seen with this "Service Pack" (more like an OS upgrade), it shouldn't turn out as bad as many people thought. Some have said that SP2 will render some programs virtually inoperable, but in the case of a home power user such as myself, everything is running smoothly. Hope it's the same for everyone else.
