Samsung has made some design changes to the second-generation Galaxy Tab tablet it was showing off last month at Mobile World Congress.

It has upgraded the original specification of the Samsung Galaxy Tab 10.1 tablet from Android Froyo 2.2 to the made-for-tablets Android 3.0 Honeycomb OS. This should make the 10.1in screen tablet more in line with the hardware specification of the Motorola Xoom which also went onsale in the US last month and was the first tablet to launch on the Google Android Honeycomb platform.

Samsung has also announced today that there will be a second, 8.9in screen Samsung Galaxy Tab 8.9 that is just 8.6mm thick. This makes it 0.2mm thinner than the Apple iPad 2 (onsale in the UK this Friday, if the hype had escaped you). The 10in model weighs 589 grammes while the smaller Galaxy Tab is a mere 470g.

The Samsung Galaxy Tab 10.1 and Tab 8.9 both come with 1GHz dual-core processors and have a 3Mp main and 2Mp secondary camera built into their frames. The WXVGA screens will support 1080p HD video and Flash playback. The tablets will have 802.11 b, g and n Wi-Fi but also support 21Mbps network speeds. The tablets will run the Google Chrome web browser and Google Maps. Samsung preloads its Tab range of tablets with Samsung Hubs including the Reader Hub for e-books, a Social Hub for keeping on top of social network messages, and a Music Hub for audio entertainment.

The Samsung Galaxy Tab 10.1 was originally unveiled as an Android Froyo 2.2 tablet - a scaled up version of the Google Android smartphone OS. Samsung has now upgraded the tablet to run Honeycomb, the first tablet-specific Android OS

The Samsung Galaxy Tab 8.9 is a wafer-thin 8.6mm thick - an all-important 0.2mm thinner than the Apple iPad 2
