This review refers to the WiFi & 3G version of the tablet. I opted for the Galaxy Tab, as it was really important for me to have a tablet with SIM-card slot in order to surf mobile can. For me this is the meaning of such a device and I've been using it now for about 2 weeks for the mobile Internet, but also at home in the Wi-Fi network. The 7 '' are big enough for a good representation of the web pages, also easier to handle than 10 ''. You can hold your tablet well in one hand and operate. Moreover, it is very light, so perfect for the handbag or backpack. It runs quickly and smoothly, the phone function is also fine, but of course it's a bit uncomfortable to make calls with a device of this size. Therefore, I use this a very spartan cell phone with a dual SIM card. But you can also connect a Bluetooth headset and make calls. W-Lan and mobile internet work fine. Compared to more expensive products of the competition Here the price-performance ratio;) The 16GB internal memory are not now an incredible amount, but in my opinion sufficient. About Micro-SD card the memory is expandable and I think that is sufficient absolutely. Synchronization with gravel over wireless works well, connection is fast and there is the need to not always have the USB cable while already enjoyable. Only strange I find the power connector plug which consists of 3 parts ... I have not seen before so, but is actually okay, because you as the USB cable just infects the power plug and the principle saves a cable. Each is considering buying a tablet and I can 'get there by 7', the Galaxy Tab 2 only recommend. Conclusion: A great product at a handsome price. I have a lot of fun with the device and am absolutely satisfied with the purchase!
