The screen is very nice on the Axim, however, max brightness and refresh rate are slightly lower than on the iPaq, as well as a slight size difference 3.5" Axim, 3.78" iPaq.
With that said, the Axim 400Mhz is hands down better than my iPaq 3955! 8O I don't know what was done to the software on the Axim however it is more responsive than my iPaq and I really like the fact that the CPU auto-scales based on required processing power, that is why it is called an X
scale after all. Oh yeah, NO MORE BULKY SLEEVES!!!
And finally, at less than half the price with more ROM, a CF slot, removable battery, and super cool cradle with extra charger/neon blue Dell logo built-in, I can see why atleast 4 people at my workplace have already ordered the Axim!
Cheers!
