Pros
Products are very complex and interesting, lots of chances to work on threading, memory issues, performance tuning, scalability, and newest technologies. Apps are metadata driven, also rare to get to work on these. Pay is good, managers are (most of them) good to work for, and most teams seem to have very good work-life balance. Company is doing well and has a chance to really explode.
Cons
Pleasanton can feel a long way from the Bay Area. There are a few senior people here who aren't easy to get along with, but most of those kinds of people have been weeded out over the last few years. 3 weeks of unpaid shutdown give you lots of family time, but they come at the expense of getting paid (or you just use your PTO for the shutdowns, which most people here do.) It can still feel a little more "corporate" here than in Silicon Valley (but you're not working 70 hour weeks either).
