Seems i’m on an HTML5 / Javascript streak this week. I’ve been testing and checking out the capabilities of the SB1 device from motorola.
This nifty device comes packed with HTML5 and javacript, from rhoelements (previously known as rhodes), and can do quite a bit of things….Looking forward to building a production app with this device – including offline feature (yay HTML5!)

You should check out http://www.loopdoodle.com, it used HTML5 and we would love some feedback from bloggers like yourself. So, if you have time, please go check it out. Thanks!
