Oh, the information age we live in! Not only devices leak straight from factories or absent-minded employees these days, but also an hour before there much-hyped presentation.
PreCentral managed to get behind the curtain of the preparations for HP/Palm "Think Beyond event", and got the info about a 1.5 pound 10" tablet with 0.51" thickness, which is to be called the HP TouchPad, and was known as the Topaz before.
The 10-incher had some really tiny phone to keep it company, which is really intriguing. That is probably the low-end teen phone, which was named Castle. The webOS munchkin is supposed to appear on Verizon, Sprint and AT&T as a Palm Pre version for the younger crowd, but is lacking a physical keyboard.
Other than that, these specs coincide with what was leaked before, so most of it will probably turn out true today - dual-core 1.2GHz Snapdragon chipset with up to 8 hours of battery life. We'll know very soon, stay tuned for our coverage of the HP and Palm event. Finally some great news for webOS fans.
