The Palm Pre had wireless charging early on. It was actually better-implemented than Qi, in that it used magnets in the charging stand and phone to automatically center the phone on it when you dropped it on there, and hold it securely.
This was A YEAR before Qi!
Another neat feature it had was unified messaging. The messaging app did SMS as usual, but you could also sign it into all the IM systems of the time, including AOL, Yahoo, Google Chat, and even your own JabberIM servers.
All your contacts/buddies/etc. were in an organized list.
This was likely one cause for the poor battery life, as the phone had to remain connected with multiple TCP sessions to each messaging service.
The slide out keyboard was nice, but admittedly I've gotten faster at typing on an on-screen keyboard than I used to type on that.
The Palm Pre's WebOS platform could have been a lot more, if it had gotten more support from Palm, and HP which bought it out. Unfortunately pretty much all contenders sorta gave up once it was clear smartphone OSes would be a duopoly (Android, iOS) going forward.
Welcome to all who regard dragons well.
