These developers gave the TouchPad a new life by porting Android on it. Now the Android 4.2 Jelly Bean version has been updated through the CyanogenMod custom ROM - a third party modification. Since this is an experimental development, some components are still non-functional.
The HP's TouchPad is still being sold by some of the retailers across the globe and mostly online. For instance, the website iBhejo is offering this famous tablet for Rs. 17,730 and eBay has some listings for around same price.
