I'm just so thoroughly annoyed with this stuff, I had to swap my SP2 once, luckily the store was local to me about 5 minutes, but the Microsoft Store is all the way across town a good 45 minute drive from where I live. This isn't an Apple vs MS thing, but damn, I've owned at least 10 MB Pros, Airs, 3 iMacs, and NONE have had Quality issues, both MS items I buy and both of them have issues out of the box? That's tough for me to swallow. I'll decide by the end of the day if it's worth hassling. Maybe I'll just go back to what I know, I gave up MS cold turkey in college and swapped to all Mac stuff. We own 2 Macbook Pros, 3 27" iMacs, 2 iPads, 3 iPhones and countless iPods, but I loved the tablet'ness of the surface, wasn't totally happy with the screen size of the SP2, so upgraded to the SP3.... It's pretty, but it sure doesn't replace things like MS says it should.
I don't really get why the entire computer slowed down to the point that it was almost unusable. After cooling down, it started working fine again. I've heard a lot about the throttling for the SP3, and it sure hit, the thing was jerking and skipping all over the place, I'd go to write something and 2 seconds later 10 words would show up, I'd go to delete and the cursor wouldn't move and then all of a sudden 5 words would disappear, I'd go to enlarge a window, and it would jitter open or closed visibly hampered by the throttling the SP3 was enabling.
*While this means nothing but anecdotally, I was a fairly competent tech support rep in college, did my fair share of programming, graduated in computer engineering, so I have a pretty good feel for checking the basics, the computer has very few programs installed, the CPU was sitting at 2% utilization for well over 30 minutes, and never fully cooled off even after restarting the computer twice, and it took a full 35 minutes and a complete shut down, then a cold boot to get the computer to go back to normal.
Upon my first reboot, it went back to normal for about 1 minute, and then it started skipping and jittering again, then I restated again, this time same thing, used it for another 10 minutes and decided to try to shut it down instead of just restarting it. After shutting it down and letting it sit for 2 - 3 minutes then booting back up, after 35 minutes of the jitters, it finally went back to normal.
