Here is a quick summary of some of the technical issues that are related to the Droid:
1) No Voice and Data at the same time
If this is a deal breaker for you, then not only is this phone not for you but Version is not for you. Work-around: If WiFi is available (like at you favorite Mc Restaurant) data can use it while you are on a voice call.
2) No Voice Dialing through Bluetooth
Apparently you have to voice dial Through the Droid mic and then push the bluetooth "button" on the phone
3) No dedicated call and end hard buttons on the phone
This is something we will have to get used to. Personally, i will give up my dedicated buttons for a larger screen.
4) No "Pinch-Zoom"
This was not implemented in the browser, yet. The speculation is that the powers that be did not want to run into Apple's legal caims surrounding the name and or use of that gesture. <I am sure that this will be resolved, soon>
5) Slide out Keyboard
Some people hate it and some don't. It is something we will have to get used to, I guess
6) Not a "world" phone
This phone is a CDMA only phone, no GSM.
Are there others? Sure there are. I wanted to quickly summarize what we have learned.
Hope this helps
