Recently, I buy a tablet called HP touchpad, it has excellent hardware: 1.2 GHz CPU, 1g RAM, 9.7 inch screen. the built-in operating system for touchpad is HP WebOS. in point of UI view, WebOS is beautiful and apple-like. but there is main weakness of WebOS: lack of software applications. like apple store or Android Market, HP also have the online application marketing called app catalog. but there are just have little of apps.
The CM team do a amazing job, they made Android port for the touchpad. to experience the touchpad with Android system, I updated my touchpad to Android. generally this ROM is fast and useful even if in alpha version. of course some bugs in alpha version, to feedback to the CM team. I need connect the my touchpad with wired USB line with ADB tools.
