As Borisb said, Froyo is necessary due to the minimum app requirements now which is one of the reasons the delay is a disappointment. Also, I was also really hoping for the speed boost when it is released but that doesn't sound hopeful. It sounds like once they get it working we'll be lucky if we keep it at the speed it's at now.

I was playing with the newest Kindle recently and the new Pearl display is really nice but what really impressed me was the speed at which the screen redrew. For an e-reader it was fast. I would love to see that speed on the Edge.

What I need to see on the Edge to make me really happy:

1. Big speed improvements for the tablet and e-reader. It does feel rather sluggish.
2. Market access (I know this is a Google issue)
3. Landscape mode on the e-reader.
4. SDK release - I want to develop for the Edge but I am not interest in only developing for the Tablet side so the SDK would be great.

I still recognize the Edge for what it is - a very useful tool, but, there is definitely room for improvement.
