This can be considered a followup thread to last weeks "impressions after 6 days" thread. I'm going to preface this with a slight spoiler..... This is the best smartphone i've ever used.
I've been downloading apps, and trying different things out. Getting the thing set up the way I like it. It really is much like a PC in this way, certain apps need to be installed to take full advantage of the power of the OS.
One app I absolutely recommend if you are connected to an Exchange server is Touchdown Exchange. At $10, it's a steal. The one absolutely killer feature it has over the built in Exchange client is the ability to auto-sync subfolders. It is for this reason I purchased the full version after using the trial for 25 minutes. Not only can it sync subfolders, it has the ability to pick which folders you want to sync. So it's not an all or nothing affair. It also has a nice interface and comes with a few nice widgets.
Another app I purchased is the Remote Desktop app (the one that's almost $20 in the market) - it's well worth it. I set up a domain name for my home PC and server through DynDNS and set up some port forwarding rules on my router. Now I can connect to my home PC from my phone. If I need a file, I can mount the phone's SD card as a remote drive on the home PC and copy it right to my phone over the 3G network.
It is this open-ness, this ability to make the phone do what YOU want, that makes the Droid such an excellent device. Some people may gripe - "I don't wanna spend money to make my phone have excellent Exchange server support, it should come built-in" - well, I am afraid that a PC-like device such as the Droid might not be for you, then. Much like a PC, if you don't like the software on the Droid you can download something you like better, be it free or paid. Think of the Android OS and accompanying software as being like a fresh Windows install. Yes, there are built-in apps; but ultimately you end up installing something better. If the built-in Android mail app is Windows Mail, the Touchdown software is more like the full version of Outlook.
Getting the Droid has proven to be a paradigm shift in how I look at a smartphone, no longer do I rely predominantly on the phone aspect of the device. I use it more like a netbook. And when I need it, the phone works well too. I used a BB Storm 9530 in the past, and found it to be much more limiting in day to day use. Even the Exchange support on BIS was severely lacking, and unfortunately, none of the 3rd party Activesync software did what I needed. I am glad to have switched to the Motorola Droid; although I am thankful for the time I spent with my BB, it got me into the world of smartphones. I don't miss waiting up late nights for a leak to make the device work well, though. I honestly don't spend much time thinking about my phone's OS anymore, and it's a beautiful thing.
