700w keys a little bit too small for my fingers
I like the qwerty keyboad on the 700w overall, but the keys are a bit too small for my fingers when typing fast. I have been typing for over 40 years, and know the keyboard layout very well. I notice that when I type fast on the 700w, my fingers hit the correct keys, but also occasionally overlap onto the adjoining keys. Sometimes the adjoining key is displayed in the document instead of, or in addition to the desired key. The first key touched by my finger was the correct key, but due to the relatively small key size, my finger hit the edge of the adjoining key. If I slow down my typing speed to concentrate on hitting the desired key exactly in the center so the adjoining key won't be accidentally depressed also, everything is fine.
It would be nice if the keys were a bit larger, but that would probably negatively impact the form factor. The best PDA/Smartphone keyboard I ever used was on a Sony Clie UX50. The keys were larger enough to allow me to type fast without any concern for depressing the adjoining key as well.
