Open Home, Ahome, GDE, Panda Home, those all I believe offer customizable number of homescreens.

I prefer GDE if only because it has a linux like feel to it with cube and stretch like animations, but Open Home is also good.

Yeah I'm a fan of Open Home if you want more homescreens. I would leave it on the default theme though. It's a little laggy on my myTouch but should be fine on the Droid.

Another homescreen replacement app that I LOVE is SlideScreen. This probably won't help you out because it doesn't offer additional homescreens. What it does is offer direct access to Gmail, texts, calls, Twitter, stocks, calendar, weather, etc. Plus it is beautiful and it runs fine on the myTouch meaning that on the Droid it would be smooth as butter.

Well i would think that the 2.1 update would have the nexus one home screens. i would wait until you have it at least till you make a decision.

You can simply install the "home" application from Android 2.1 (I did it on mine, without any root implied).

You download the file here : http://dl.dropbox.com/u/1120771/Launcher2.apk

Then you copy it to the SD card. With either ASTRO file manager, eoeAppInstaller Pro or any other APK manager available on the Android Market, you install it. Next time you press the Home key, a new window will appear. Just check "Use by default" and then click on the new app. You'll have a brand new Home app, official with 5 home screens and a few candy...

And doing a web search, you'll also be able to find other native 2.1 app like "Gallery" (which is awesome!)...

@MollyWhite:
I understand there is a "one click root" option for the G1 and maybe even the MyTouch, which I would imagine would make it super easy. Maybe someone here can supply you with a link. However, if you have any other phone I'm not sure the "one click root" option will be available to you. You'll also want to make sure to backup your phone to a hard drive (dont know if the "one click root" will include this process).

One of the major risks to rooting your phone is "bricking" your phone (aka making it about as useful as a brick). I'm not sure if backing you phone up will protect against this, or not (although i think it does). The other risk is killing your 1 year warranty.

The benefits include almost limitless versatility with the operating system. Once rooted, people can tweak Android to do so much more than what it currently does. Roms (variations of Android) can be installed to...

-improve the phone's processing power
-tether (use your phone like a wifi modem for your laptop)
-multiple home screens
-voip calls
-software that make it look like other phones (palm pre, iphone, nexus one, etc).

you can look these roms up on youtube.

PS: Forgive me if I was talking down, I hate to assume people know all this jargony stuff. Personally, it took me forever to catch up to the community.
