The SP4 is a brilliant piece of hardware, WHEN IT WORKS. That's saying a lot coming from an Apple guy. I believed enough in the SP4 to not give up when the first unit crashed beyond repair. So I replaced it. The experience with the second SP4 is far better, but it's still frustrating. Display driver crashes, slow wi-fi, intermittent pen disconnects and screen freezing. When it all works its a fun experience. When it doesn't work, I'm ready to return it.
MS blew the launch of SP4 and SB. Both platforms are experiencing their fair share of problems. Too many to be considered a successful product launch. The question remains, will MS make it all right for the consumer? I sure hope so. I'm counting on them to do the right thing and resolve the issues as quickly as possible.
Ready to give up? Not yet.
1) TH2 comes out tomorrow. Hopefully that will fix most if not all of your problems.
2) Jump on the insider build program. That's usually out in front of the regular patch crowd in terms of fixing driver problems.
3) Reset, re-image the machine.
