Motorola Mobility's Webtop concept, which enabled its phones to act as the brains of a laptop or television entertainment hub, has quietly been killed off according to cnet.

Webtop was software that allowed a Motorola smartphone, like the Atrix 4G for AT&T, to be docked in to a special laptop accessory and run with some computer functionality such as the browser. When it was unveiled, many had called it the future of mobile computing.

Unfortunately, the execution wasn't so smooth and sales were disappointing. Motorola, one of Google, said today that adoption wasn't sufficiently strong to justify devoting more resources for the project. Webtop will no longer be visible on phones, starting with the Photon Q, Droid Razr M, Droid Razr HD, and Droid Razr Maxx HD.

Full statement below:

Motorola's Webtop app helps users extend their smartphone experience to larger screens. While consumers around the world have adopted Webtop and the concept spurred a lot of innovation in the industry, the adoption has not been strong enough to justify continued resources being allocated to developing Webtop on future devices. We have also seen development of the Android operating system focus on the inclusion of more desktoplike features. Beginning with Photon Q and Droid Razr M/Droid Razr HD/Droid Razr Maxx HD, we will no longer be including Webtop on our products moving forward.
