It'll be nice to see what Intel does with Gingerbread. Android is based on a Linux kernel and is far less likely to have security issues.. That is, of course, if Intel doesn't build them into the OS.
The Motorola Atrix already has the ability to be used via faux laptop with docking port. I can see the duo being very handy for business professionals who travel and want a computer to update data on-the-go. The available 'fauxtop' is only 2.4lbs. I wasn't sure on voice call capability in netbook mode so I found this
Wall Street Journal article:
When you make or receive a voice call while the phone is docked, you must rely on the phone’s microphone and speakers, hidden behind the screen of the dock. As a result, calls sounded muffled on both ends, even though the phone automatically switches into speakerphone mode. Motorola says it is working on this issue.
I think a netbook is good choice for kids. Something to type up homework, do research, etc. No drive to install games, but enough utility to be productive. There again, I wouldn't go out and purchase one because when I have kids there will be multiple working computers in the house.
I can't see getting one for myself. No optical drive and minimal graphic capabilities are my biggest complaints. I'd rather have something to watch movies/DVDs and keep entertained when not at my own home. That, a netbook can't deliver on.
