Motorola Droid :: Droid Vs Ipod Touch Vs Archos 5

I bought the droid, love it (using it as a wifi enabled media player with tons of apps), and can still return it penalty free, but am not impressed with the call quality. I am thinking about either getting the ipod touch, dropping the verizon service and using the droid, or getting the archos 5. I dont need GPS, phone, or the camera. I have a few questions.

1 Is this a stupid idea? I can get a 64gb ipod touch for $399. The 16gb droid will be $375 after early termination penalty.

2 How will it function without verizon? I will only be using data downloads where WIFI is enabled, everywhere else it will just be a stand alone media player.

3 I would like to use skype over WIFI. The skype lite app for droid does not allow that. Does the ipod touch require you to use an accessory with a microphone?

4 Battery power. I read on these forums that turning off the droid does not stop the battery from draining. If i turn the droid off and dont use it for a week, will it be dead?

5 How about Archos?
