Hi all. Thinking of upgrading my momo11 bird with a quad core tablet, but there seem to be quite a few to choose from now. my requirements are: 10 inch screen, quad core, preferably 2 gb ram, sd card expansion, hdmi out, at least android 4, good wifi, must have full android market and a good battery life. My budget is around the £150-£175 mark, which I guess means I have to go chinese. I've seen the ainol novo 9 spark, onda v972, chuwi v99, ampe a10 and ployer momo 20 all seem to fit the bill. Any recommendations. Pros and cons? With real user experience? Thanks for your help.
