I loved my A500. Unfortunately, it is probably somewhere on the DC beltway smashed into a thousand pieces! One of the greatest things about it was the USB port. I had my tab for a year, and I used my portable hard-drive a lot with it. It seems, though, that the USB capability was also a disadvantage. The higher voltage it took to have a powered port used much more battery and required a proprietary charger. The A200, I believe, has the same charger, but it also has similar short battery life. The A510 has much greater battery capacity and life and charges by USB, but it doesn't have a full USB port. So there is a tradeoff Now, I want to replace it and am wondering what this list recommends. Most of the newer tablets don't have full USB capability. What is the best alternative/option to the A500?
