Yes I read the same thing about the HTC products,
HTCClassAction.org - Because HTC dropped the ball, and it's about time they pick it up!
My friend has the Tytn II it is quite good he does not notice too much of a problem, he does not use the touchflow though says it is quite crap response wise.
I saw a Tytn II in Sham Shui Po for 4500 and you can get a good discount at the MK computer centre as well. The tilts are a good device, I like the cruise it is smaller and lighter but lacks a keyboard (always something). The new LG ks20 looks good and light, for under 4k pretty good value, but the toggle stick looks like it would get in the way when you put it in your pocket.
