Hi
There's allot of improvements, shells, skins..... that are finger-friendly...
I Really like it finger-friendly, it is more comfortable and usually looks good.
I've noticed that the TOUCH PAD of the IPhone is very sensitive for finger touch, while the Hermes needs a very hard touch (Relatively).
Is there a (hard) sensitive touchpad (Digitizer) for heremes ? (something more finger-touch friendly...)

I was looking in ebay, and noticed that there are 2 kinds of Digitizers, does someone knows the difference ?
Digitizer G1 (http://cgi.ebay.com/HTC-Apache-Prodigy-Hermes-TyTN-Full-LCD-Screen-Gen-1_W0QQitemZ300176702675QQihZ020QQcategoryZ20336QQr dZ1QQssPageNameZWD1VQQcmdZViewItem)
Digitizer G2 (http://cgi.ebay.com/HTC-Apache-Prodigy-Hermes-TyTN-Full-LCD-Screen-Gen-2_W0QQitemZ270221419416QQihZ017QQcategoryZ20336QQr dZ1QQssPageNameZWD1VQQcmdZViewItem)

Tnx.

I'm afraid neither of those will do what you might think they'd do. The term digitizer refers to a module that consists of a matrix to sense particular change of state in one (or more) given point(s) and translate that as coordinates data in digital form.
There are maybe 2 revisions of them in the ebay links you attached but I don't think they work differently, perhaps one has better sensitivity or responsiveness.
Digitizers activated by pressure works differently than ones activated by mere touch (capacitance). The first is noticable by the requirement of stylus or something to "press" a point to "short circuit" a tiny area in 2 thin layers that are stacked together, they know where the "short circuit" is and report that as the touch point. The latter is activated by the fact that the touch actually alters the "electrical charge" of that particular area.
Common portable devices nowadays still use the press-type, usually it is completely separated from and installed on top of the LCD (if you look closely to your screen when it's turned off you'll notice tiny dots which is the matrix), that's why sometimes they slide around and you have to recalibrate your touch screen. I hope this makes sense.

KaiserVideoDriver has it correct. That's why the iPhone has such a sensative touch screen. Also, I believe that the resistance based touch screens that our phones use are not capable of registering mulitple touch pionts, which is why Apple had to go the opposite route...in order to facilitate the multi touch interface.

From time to time I try and use my Hermes without the stylus, but I constantly find myself either tiring of the constant finger prints and smudges, or I get aggrevated over the touch screen seeming to have a fit from time to time and register touches wrong. It seems to be calibrated for the stylus (i.e. a small, firm touch point); the larger, spread out touch point of a meaty fingertip seems to drive the screen crazy and cause it to register the touch to either of the upper corners. Infuriating when it closes a program or tries to cancel an SMS on you.
