Excellent post last month on the Google Gears blog. We have a few people that like to live in the countryside where all they can get is high-latency satellite broadband. I'm myself considering buying land here in Chile where the best internet access I may get for the foreseeable future is 3.5G (UMTS/HSDPA) (not sure what the latency is, but probably not too good). Waiting 10+ seconds between each salesforce.com page load for instance is a real productivity killer. Google Gears is important infrastructure stuff that Microsoft should pay very close attention to.
