I've stopped building. I used my Cr-48 for two months, day after day.
Unfortunately, I was granted an i7-based laptop by work. You can imagine my position.
The Cr-48 is a great appliance. I'll probably write a summary in the next few days.
Things will be better when Tegra and other dual-core ChromeOS devices hit the market. For now, I may be signing off. Maybe.
