Summary: Main purpose of purchasing was for school, reading ebooks. I compare a lot of tablets at 7". At such price, it's worth buying. it can do anything you need. doesn't bug nor lag for a quad-core. Plus you can add additional memory with a memory card which not many tablet has this feature. Overall this is still a decent devices for travel, school, small business.
Summary: This device is a great value tablet. You pay what you get, a decent tablet with some nice features, a great display, but with no real horse power in the GPU side, 1 GB of RAM so multi-tasking might be a little laggy; however if you close all the unused apps this can be avoid, but for $150 it's one of the best tablet you can get. The main use for this tablet would probably for E-books, E-textbooks, media consumption.
Pros: Great value, mircoSD slot, great IPS display, decent battery, good build quality, ASUS apps are good, ok camera.
Cons: CPU is gets the job done, but don't expect to game on it, some lag, uses Andriod 4.2.1
