1) While it's nice that it has a keyboard dock, it appears that the dock may only support the iPad in portrait mode (they placement of the connector on the long side of the iPad made it seem a bit precarious for putting in a docked mode).
2) Nothing said about mouse support. Seriously, if I'm going to be using it for any type of document creation (and they seem to think people will, as they're providing iWorks in the app store), I don't want to have to use the screen for copy and paste. Lack of mouse support would be a killer for me.
3) Main screen is nothing but icons to get into applications. With more screen real estate there should be support for widgets on the home screen (as I understand it, iPhones and iPod touches don't allow that--one must jailbreak a phone and do it manually).
I'm sure there are more, but those are some things that pop right out at me. As others have said, it really looks like the worst of both worlds. Not as portable as a smartphone, not as good at document creation as a netbook or notebook. eBooks, papers, and mags seem to be the only things to gain from this device.
It depends on how the Exchange server is set up. For industries that demand security, such as healthcare, Exchange servers tend to require that mobile devices support things like encryption and remote wipe. In order for the device to connect, it has to tell the server that it supports any of these capabilities required by the server. Android's default email client doesn't. The Touchdown app does report capabilities back, but it's basically fudging the truth in order to connect (that's my understanding, anyway). Some admins have glommed on to this trick and are refusing to let Android devices connect at all.
So no, Android isn't ready for the enterprise. I have the HTC Eris and love it. I work at a research/teaching hospital, though, and probably wouldn't be able to use it for work. That's fine by me, but anyone who got the phone in order to keep up with work is going to be quite disappointed.
Crazee Edeee, his prices are INSANE!!!
