I miss a bunch of stuff:
1. Touchstone. Should be technology of the decade. I have one in my truck, and another on my desk at work. It was just SO nice to be able to get into my vehicle and set the phone on the TS and have it charging and have it automatically connect to my stereo through Bluetooth. Total bliss. Now I have to find a place to put my EVO and manually hook up the juice every time. And on my desk to listen to Podcasts and music through my desk speakers it's a two-cord affair.
2. Integrated email inbox.
3. Separate control of screen off and screen lock times. Last night I was at my son's award banquet and was taking pictures and I had to leave my phone on the whole time because when I shut off the screen the phone actually locks. On the Pre I could set it such that I could turn off the screen but it wouldn't actually lock. Plus, I had a big fat numeric keypad for my PIN entry screen and could unlock with my thumb on the Pre.
4. The ability to easily control what's running.
5. Swiping left and right to delete rather than a bunch of clicking.
6. Apps that cost half as much.
7. The camera. Wasn't as flexible and didn't have all the settings, but it takes fantastic photos.
8. Being able to hook up to my wifi at home when it's set to not broadcast SSID.
9. A physical keyboard.
10. Universal search was much better, especially being able to get to contact in the firm GAL without a bunch of hunting and pecking.
Don't get me wrong, I love my EVO. But I still think WebOS is THE best mobile OS on the planet.
