mine (haipad 701) works ok, similar to my blackberry storm, not as fast as my droid response wise but usually depends on cleanliness of my finger - i opt for using a gameboy stylus as i find it easier to do fine picking - my issue is when i try to scroll, it is too sensitive and takes the flocking movement as a press
cruz macho reader: generally good finger responce..problem is that some letters have more than one type set and fat fingers will make it ask which one do you want..they do make a case with a minikeyboard, sold on ebay for 7" 16x9 display pads.usb attachment... then theres no problem..$24-30 pp
I have a resistive screen on my Archos 5IT. Honestly, it acts just like a capacitive screen, except I can use a fingernail to type - or Swype too. It's very responsive.
My Haipad M701-R screen is very responsive to light finger presses, but it doesn't always interpret swiping/scrolling with a finger (thinks you're clicking), so a fingernail works better for that.
I use an old dried-up felt pen as a stylus - much better than my fingernail, but still not perfect. I guess I have been spoiled by the capacitive screen on my iPod Touch...
