* Dell discloses specs, initial carriers

* First Android tablet from major electronics maker

* To debut in UK in early June, U.S. in summer

* Dell yet to disclose pricing

BOSTON (Reuters) - Dell Inc said its
Streak tablet computer can double as a mobile phone and will
have a front-facing camera for videoconferencing -- features it
hopes will help the new gadget compete against Apple Inc's
iPad.

The five-inch tablet will debut in Britain next month
through mobile carrier O2, a unit of Spain's Telefonica
, and Carphone Warehouse. Dell has yet to
announce pricing for the Streak, which it said will appear in
the United States sometime during the summer.

The company formally unveiled the Streak on Tuesday, after
Chief Executive Michael Dell gave the tech world a glimpse of
the tablet at a conference two weeks ago in San Francisco.

Dell will become the first major electronics maker to take
on the 9.7-inch iPad with a device that runs on Google Inc's
Android operating system, more commonly found on
smartphones.

"It's portable and mobile. You can put it in your pocket,"
said IDC analyst Will Stofega, who has tried out the device.
"It is interesting and infinitely usable."

Android is gaining ground on the iPhone in the smartphone
market, but it is not yet clear whether Google and Dell will be
able to take on Apple in the tablet market.

"Can Dell sell millions of these? That's a tall order.
There is certainly the potential. If it is priced right and if
the thing sort of does what it's supposed to," Stofega said.

The Streak, which will have a slot for external memory
cards, is part of Dell's plan to expand sales of mobile devices
to help boost revenue after it has slipped from being the
world's largest PC maker to No. 3 by volume.

Forrester analyst Charles Golvin said he was skeptical that
Dell could catch up with the iPad in one key area.

"Dell's entry into the phone/tablet market is marked by
some nice hardware, but Dell still lacks the one element that
will matter most in differentiating itself in the flood of
Android devices, and that's skill in software," he said.

More than 200,000 software applications work with both the
iPhone and the iPad, which was launched in the U.S. in April
and goes on sale internationally on Friday.

Stephen Felice, who runs Dell's consumer, small and medium
business divisions, told the Reuters Global Technology Summit
in San Francisco, last week that the Streak would be aimed at
consumers but that the PC maker's goal is to eventually build
tablets for large corporations.
