I have jumped ship from a 3GS to Motor Droid in November 2009. The main reason was that ATT has no 3G at my work place; while Verizon has! Ten times faster!
The major advantage of Android is the multitasking ability. Another plus id that I can download some podcast over the phone without having to sync with itunes. It did lack some apps that I used on iPhone, but overall it gets things done. The one major hurdle is having to update each apps individually. Also the minimal sync function with Mac (double twist) makes photo and video sync a little more complicated.
For email and calendar, Android really nailed it. It supports multiple exchange accounts and gmail accounts. Now I quit using me.com for calendar and totally transfer to Google. And it is free!
Just recently I started feeling the Droid is a bit lagging and was looking for some android phone with faster snapdragon processer and extra features. HTC EVO 4G surfaced out but the slightly lower screen resolution held me back.
What I ended up doing was rooting my Droid! And it's all for the speed. Overclocking!! Through help on droidforums.net I put on Bugless Beast v 1.1, along with P3droid overclock module. And I couldn't be happier! 1.25 GHz compared to stock 550 MHz! And the battery management software still keep it running cool and long. Many other benefits also come with rooting, such as system backup and wifi tethering.
Now every time I open photo gallery app. Everything just renders in a snap! And this souped upmotor Droid should keep me happy for a while until 4G coverage spreads wide.
