Two things about that illustration:
1) They are not to scale
2) HP neglects to offer a front view of the Veer without keyboard
iPaq PPC: 4.47″ x 2.78″ x 0.5″ – 4.4 oz
HP Veer: 3.31″ x 2.15″ x 0.59″ – 3.63 oz
The original small iPaq Pocket PC had one of the most startling screens of its time. It was so good that it looked like it was painted on. As they moved to the next model, it lost that screen, which was a huge disappointment.
Anyway, looking at some Veer videos today, I remembered the Pocket PC they once did and wondered which was smaller.
