I’m not going to try and put down the Android platform, since I haven’t played with it, and, at least on paper, it actually looks like quite a compelling software platform.

The first iPhone hardware was widely and rightly criticized for it’s recessed headphone jack

I get that there’s no desktop sync, it’s all linked to your google account and all happens in that ill-defined “cloud.”  I’m not sold, but I get it.

As for the hardware… only 1GB of memory, but upgradeable with an SD card slot, so whatever - I’m not going to argue.

However…

All I want to ask about the new G1 Phone is: How do you make an all-in-one communication/media device that doesn’t have a 3.5mm headphone jack?  Why the need to purchase an extra adapter for what’s supposed to be an all-in-one device?

Audio output through the USB jack is non-obvious and requires an adapter to use the cheap box-store headphones.

The first iPhone hardware was widely and rightly criticized for it’s recessed headphone jack - something that budget headphone designs quickly adapted to — as making headphone jacks fit the iPhone didn’t harm their usability in any other device.

I’m nitpicking, for sure, and something that’s easily corrected in future hardware revisions, as with the iPhone 3G… but, considering that music (the phone ships with an Amazon MP3 Store app) and video (YouTube) playback are two of it’s biggest advertised features,  it seems like a glaring omission.
