Allow me to interfere. IŽm Skywaves husband, and too, after her boasting with her new Tattoo's possibilities, a hapy owner of a HTC Tattoo.
No, we haven't tried the Hero. So we can't compare neither the touchscreen nor the camera.
We've had a Motorolla K1 and a Nokia 5300. Both cameras, with about the same specs, were better than the HTC's. The Tattoo's camera can't be used with a barcode reader due to its lack to focus on near objects (fixfocus) and it has a lousy whitebalance.
I don't think that a camera i a mobile phone has to be top class, but a little better would be nice. But if you don't need the phone to act as your primary camera and don't have to use a barcode scanner, youŽll be fine.
As for the touchscreen, people who have used a capacitive screen, do not like the resistive one in the Tattoo, because it needs a tiny amount of pressure, where a capacitive screen is a "real" touchscreen. As we have no experience with other touchscreens we are very satisfied with the Tattoo's.
My wife has, on my advice, chosen the Tattoo over the Hero, especially because of its smaller size and because of the newer android version (1.6 where Hero and Magic come with 1.5), which supports danish characters. And also it comes with a substantially lower price-tag
The screen size is OK, even for me, who has to choose the largest size of gloves, if I have to get some. Larger screens make larger phones. How much will you carry around? If you want a large screen, buy a laptop
best regards and good luck with the Tattoo or what you'll decide on
