The MobileDemand Flex 10B is essentially a Windows tablet that comes in a prebuilt protective case. And it comes with an included keyboard too that has a snap mount on it to attach to the tablet. It probably is the best rugged laptop and the best laptop that is both cheap and ultra lightweight.\r\n\r\nWhy We Like It - MobileDemand Flex 10B\r\nThe MobileDemand Flex 10B Ultra Lightweight Windows Tablet, as the name suggests, is an entry level lightweight, rugged tablet that comes at a very enticing price of just $665. And at 2.07 lbs, it really is as light as MobileDemand claims it to be.\r\n\r\nPower & Performance\r\nThe performance of the MobileDemand Flex 10B is not that bad considering the price. The Intel Celeron N4100 quad core processor should be able to handle most low stress workloads perfectly fine. And while the 4 gigs of memory is pretty low, you don\u2019t really need anything substantially higher unless you\u2019re into opening way too many tabs at the same time. If you need a better performing rugged laptop, get the Lenovo ThinkPad P52 instead.\r\nBattery\r\nOn average, you can expect about 6 hours of battery life from this tablet, which is actually better than we expected. It sports a 3000mAh battery. We would have gladly traded the lightweight aspect of this laptop for a bigger battery (because there\u2019s more than enough space for one), but at this price 6 hours is nothing to scoff at. If you\u2019re not satisfied, you need to rather grab the battery life champ LG Gram 17 ultrabook.\r\nPorts & Expandability\r\nFor a tablet of this nature, it actually comes with a lot of different ports. You do get both USB Type A (USB 3.0) and USB Type C. And you also get a mini HDMI port for display output. And as always, there\u2019s also a 3.5mm standard headphone jack. The only other rugged laptop that can probably beat it in terms of available ports is the Panasonic ToughBook.\r\nBuild Quality\r\nThe build quality overall is excellent. The tablet truly is built like a tank overall. The protective case like design on the edges prevents the glass display from shattering due to the impact of a drop. And the whole modular design also is a big plus point in our book.\r\nValue\r\nThe fact that this tablet can be bought at under $700 is pretty impressive, to say the least. So the value proposition of it already is very good, especially for field workers. And while things like the proprietary charger, low-res display do dent the value aspect of the Flex 10B a bit, overall, it\u2019s an excellent value for money buy.\r\nMobileDemand Flex 10B Wrap Up\r\nWell, looking at everything above, we can conclude that the MobileDemand Flex 10B is a pretty great budget rugged tablet\/laptop. If you are not going to perform any demanding work, you can go for it with your eyes closed.
