There is only one Motorola Droid on the market in the US as far as I know. There are other android phones on the market, and of them I would say the Nexus One is slightly superior to the Droid, but they aren't compatible with the same cellular networks so if you are on Verizon go with the Droid, if you are on ATT or T-Mobile then go with the Nexus One.
What I love about the Motorola Droid - well, one of the hundred things I love about it - is that is has a LOUD speaker. This proves well for both speakerphone calls and the built in music player. I can sit it on the bathroom counter and hear the music over the water while I'm showering. It has crystal clear sound, and has never dropped a call.
Today my Darling Bride needed to see a chiropractor. IMMEDIATELY. I used Voice Search and said "Chiropractor" to the Droid. It googled the term and brought up 3 of them near me. I clicked on one, hit "directions" and "navigate" and it gave me turn-by-turn navigation guidance all the way to the doctor's office. Things like that are priceless to me, and saved me a ton of time looking through the yellow pages, making phone calls and asking directions.
With the Android Applications Market I have downloaded music players, games, utilities, facebook and news widgets that keep me entertained and in the know, up to the minute.
All this in the palm of my hand! I hope this helps. You cannot go wrong with a Droid.
On the other hand, my son has an HTC Droid Eris. It is not the MOTOROLA Droid, which I think you asked about. It has no slideout keyboard (not that it matters much, the predictive text is awesome) and has a prettier interface... and it has seven home screens vs. the Droid's stock three (there are home replacements in the app market that increase it to 7 though). But it also lacks turn-by-turn GPS navigation. So it's a matter of personal preference.
Those are all pictures of the same model, David. All the Motorola Droid, just in various poses.
It's a multi-tasking little devil LOL
I have tried the Eris and I must say this: given the opportunity, I would choose the Droid all over again. No contest. Even my son keeps asking to see MY phone... not the other way around LOL
I had T-Mobile when I moved here and their coverage was awful. In my new area Verizon reigns supreme... but then, everywhere I have traveled, Verizon is there with phone and 3G data service! Their customer service is stellar and you can't beat the network. Keep in mind when you get a Droid that it's a smartphone and requires a $30/month unlimited data plan. And with that gorgeous screen, you may not be able to stay away from YouTube in High Quality! Just a heads up, that'll add to the bottom line. Well worth it, though. I can pretty much surf anywhere.
That's $30 unlimited DATA.
You still need a voice plan for it as well.
I recommend http://phones.verizonwireless.com/motorola/droid/#/home as a starting place.
As far as battery life goes, I can easily go all day on a charge and then let it recharge in the dock at night
(makes a great night clock!). As far as I know, you can store 1000 contacts on it, all backed up with Google.
The Droid will become your new best friend
