I was surprised there wasn't a dedicated thread to the Chrome OS (There was one from 2+ years ago) and Chromebooks.
The only reason I bring this up now is that I just won an eBay auction for a CR-48, which was the developer platform/tech demo unit that Google gave away to 60,000 people.
It comes with 24 months of 3g through Verizon, but only 100 megabytes a month.
Its basically a netbook that only runs the Chrome browser, which obviously has some limitations. The main one that I'm worried about is the lack of CPU power from the Atom processor, especially when it comes to flash and streaming video.
Other than that, the idea is that everything is already browser and cloud based, and especially for someone as invested in Google services as me, its not far off. I can access all my Docs through Google Docs, my music through Google Music, obviously browse the web, and even play the Chrome app of Angry Birds (depending on performance). It should be interesting to play with at least.
