The 3G iPad, which unveiled for sale on Friday, witnessed an absurd mix of boom and bust.

At the Web 2.0 Expo in San Francisco on Tuesday, Raven Zachary, president of mobile developer Small Society, mad an attempt to explore the territory as he recalled his experience using his iPad as substitute for a laptop.

With the launch of 3G iPad in San Francisco, AT&T's network was witnessed to be overloaded by iPhone-toting hipsters, and with many failing to get a connection- not even to set up an account so AT&T could take my money.

The iPad is unlocked, however, is compatible with Micro SIM cards only. Since AT&T is currently the only U. S. carrier using Micro SIMs, that means all are stuck with AT&T.

It facilitates immersive web-browsing experience, excellent e-mail and calendar apps, in addition to apps for playing music and seeing your photos.

Moreover, it is a boon for doctors as well as they could look at up-to-the-second patient info, architects could use it to see 3-D models in the field, and the military could make a potential use of it to help eliminate friendly fire.

Its battery backup is revealed to be more than 8 hours on a 3G connection before going kaput.

iPad Maps + GPS is absolutely stellar. Unlocked, version is compatible with any Micro SIM card.
