The last time I had a problem with my MBP's screen, it took almost a month to be fixed.
A failing keyboard is enough reason for me to wait for a version which they fix all these issues. Even if it only breaks for a "small percentage of users", it wouldn't be nice to wait almost a month without my work machine...
Apple actually sends them hardware to be repaired that is so old that they can't fix it themselves, because they don't have the necessary spare parts and experienced technicians on staff. Both of their hardware technicians have over 30 years of experience repairing stuff, and have every single certification that Apple has.
For everything Austin MacWorks can't fix in-house, they are very good about getting that stuff out to depot and getting it back ASAP, and they will do your backups and restores for you, if necessary.
If I have a simple problem, I'm happy taking that to the Apple Genius bar directly. For everything else, I don't trust anyone but Austin MacWorks.
