I was given the opportunity to have a look at the P1000 Samsung Galaxy Tab for a few days. It was already running on the Android 2.1 and the owner was keen to have the firmware upgraded to 2.2.It was rather difficult for him to do so because there is no firmware upgrade option on his Galaxy Tab (strange but true).
To start off with, I do feel strange holding on to a 7" tablet and making calls. The Galaxy Tab, by no means small for a person holding on to it. I think it is only good if the user were to use a bluetooth headset for making or receiving calls - It will not be weird then. The screen is capacitive and runs smooth even with the Android 2.1 firmware. I have no problem with it.
Apart from that, it is powered by a 1Ghz ARM A8 single core cpu and a PowerSGX 530 gpu. It supports flash and it is also equipped with a front 1.3MP camera and a back 3.15MP autofocus digital camera with an LED flash. Apart from that, it has bluetooth and supports quadband GSM and 3G. Users would have to differentiate it with the P1010 as the P1010 does not come with radio support for voice calls.
In that two days of trying, I have been able to upgrade the firmware to 2.2 and it is beautiful! The internal 16GB storage and 512MB of RAM is sufficient for everyday use. In fact, I think web browsing is good too! I have tried watching 1080p videos on youtube and it can run but the graphics were choppy. Besides that, the device is considerably light at 385g.
So far I do not have any problems with the Galaxy Tab. However, I would hope that Samsung will release a dualcore Galaxy Tab 10.1 with 3G but no voice communication soon. Battery life on the P1000 is pretty solid at one day of moderate usage.
Given the fact that the Galaxy Tab P1000 is now being sold at £256 online (brand new), I see no reason why people should wait for the Tab 10.1 though. However, we have to take into account that there are other alternatives to the Galaxy Tab, noticeably the Apple Ipad 2 and the Motorola Xoom which both have more capabilities than the P1000. It is all up to a buyer to choose... I would wait for the Ipad3...
