Exactly. You might also add that Symbian Series 90 was almost painfully slow on the 7700 and 7710 (I think the 7700 was an "extended prototype" -- a bit like the Zaurus 5000 -- and not even meant for sale to the general public). There was, in fact, one thing that did make it from the 7710 to the 770: Hildon. The user interface on the 7710 is an early version of Hildon on the Internet Tablets.
