Barry,
Funny thing - I set my drink down on a hard surface a foot away from my iPronto and it comes to life! The tilt business works just fine - using 1.8.2.
Since I only got this about 2 months ago, I can't comment on the speed, though the speed of the internet part is agonizingly slow and mostly useless due to this. I want to use the direct "eye" channel link from the EPG, but at the moment that is on-functional. Gotta do some more research. Read the online help already.
M yiPronto is having problems with the downloads of the EPG, but except for a dead iPronto tonitght, no other wake up crash issues for me. A reset fixed my problem.
