I've wanted one for a while, but since I maintain the family MacBooks, iPads, and we have Android phones, and I have an Android tablet, and I run Linux on my computers, I wasn't sure I needed another OS in the house!
But if Chromebooks can run Android apps, that might trigger me. It bothers me that I can have some convenient apps for my phone/tablet, but can't easily use those same on my computer (like 'mobile deposit' of checks - my computer has a web cam, but no go).
I guess the Chrome Browser (but not the totally open Chromium browser) has some sort of support for Android apps, have not tried that yet.
I'll say it again, though I'm a big fan of Linux, I think a Chromebook makes a LOT of sense for someone who just wants to open the box and have browser and email w/o installing an OS (even though Linux is usually pretty easy to install, it's not as easy as opening a box and pushing the power key), and w/o having the baggage of MS Windows.
If the support for Android apps is good, and touchscreen and a fold-able keyboard can be had at a good price, I think I'll get a Chromebook when I'm ready to replace/upgrade my tablet.
