Got the itch last night and picked up a Droid. After 1 days of use I am glad I got it. Moto has really turned around their product line with this. Even better my Nexus One sold 15 min after posting it on ebay! Any must haves that I should install on this?
1. Handcent
It for text messaging. MUCH better than the stock Droid app. Allows you to speak your text messages instead of typing them. Also, it can speak your messages to you and it has a few themes to choose from for display. This is probably the most popular sms app out there.
2. Some kind of battery life widget.
There are several to choose from. They offer a homescreen widget that displays the battery life. Just do a search in the Marketplace for "Battery" and select the one that you like the most. Make sure to check the comments so that you dont download one that sucks.
3. Some kind of home theme app.
There are a few to choose from. Home++ and Pandahome are very popular. I use Home++. It will allow you to have 7 home screens and horizontal orientation. The best one is Sweeterhome, but the newest version is still in beta, so you might want to wait till they release it on the Marketplace.
4. Beautiful Widgets
Has some handy widgets for Vibrate, Silence, WiFi, etc... Also, it has a beautiful weather widget that displays the time, date, and current weather. It has a future weather display that is even cooler.
5. Ethereal Synthesizer
This is just a cool app that plays different tones when you touch the screen. Will make you smile!
6. Pic Say
Allows pinch to zoom for photos. However, the 2.1 update is supposed to have this feature so Pic Say wont be necessary anymore.
7. Screen Test
Will show you if any of your Droid screen pixels are burnt out.
8. Some kind of flashlight app.
I use Droid Light. It will light up the camera flash and is very bright!
9. Other fun apps....
