I have had to do several soft resets in the first two weeks of owning my 7135, but most (all?) of those were "my fault".

However, this morning, I had my first weird instance. I took it out of the cradle, not while doing a sync, and nothing would respond (no backlight, no buttons). Fortunately, a soft reset fixed it and I did not lose anything. Not worried about it, but strange that it happened on day 13. Two more days to evaluate, but certainly am planning on keeping it.
