I've had my nexus 7 since launch in 2012. At first it was great and I loved it. But now it's giving me problems. It takes way too long to charge up (9 hours). I even bought that easyaac 5V fast charger from amazon thinking it would help. It didn't. Plus it barely lasts for 4 hours before dying. So about that new asus memo pad. It seems to be like the nexus 7 with the addition of a rear camera, SD card slot (thank god), and more powerful processor (Intel). And for $100 less than what I paid for my current tab. Is this a good buy? Can it do everything the nexus 7 can? Like be rooted, able to able to side load apps that aren't on the play store, etc?
