Samsung is expected to show off an Android-based tablet dubbed the P1000 Galaxy Tab at the IFA consumer electronics show in Berlin next month, according to multiple reports. The tablet is said to feature a 7-inch touchscreen and offer live video chat capabilities. Fuzzy photos of the P1000 Galaxy Tab device first materialised in June on AndroidCommunity.com. Since then, clearer photos of the Samsung tablet spread through the web.

The reports compare the new device to Samsung's Galaxy S line of phones, on which the Tab is based. Conflicting reports have the Tab running either a 1 GHz or a 1.2 GHz processor. Samsung would not comment on the reports.

With both front- and rear-facing cameras useful for video chatting, the Tab could offer an advantage over the iPad, which has a 9.7-inch screen. Sales of the Apple device have topped 3 million units since it first went on sale in April.

Basing the Tab on the Galaxy line of phones "is not much of a stretch for Samsung," said Jack Gold of J. Gold Associates, who earlier predicted that a number of Android tablets from several manufacturers will appear before the end of the year. "But the real question is how well an Android tablet will sell?" Gold asked.

Gold said the success of Android phones will be based on price and which carriers offer it. The future of Android devices would be helped considerably, Gold added, if they are sold in Best Buy retail stores.

The Android-based Dell Streak , featuring a 5-inch screen and voice capabilities, went on sale August 13. The Streak runs Android 1.6 while the Samsung Tab would run 2.2. The Streak sells for $300 with a two-year AT&T contract, a price some analysts have criticised as being too high.

Engadget and other sites have found the Samsung Galaxy Tablet on a UK carrier Vodafone inventory list, indicating it could first be offered there. Dell's Streak was available in the UK before the US.
