Well, after a few weeks of use, the included windshield mount finally broke completely on me and separated into 2 peices. As mentioned in the TomTom GO 910 Review, prior to breaking completely, the mount had been doing a rather poor job of keeping the 910 secure; when driving, the mount would droop down until the 910 was facing a 45% down-angle.

TomTom's support department has assured me a new mount is in the mail, and an improved mount is "in the works". In fact, the TomTom support rep told me that the mount is "a known issue that TomTom is working out, and the main reason why TomTom isn't selling the 910 directly yet." Hmmm... Doesn't really speak well for TomTom...
