Set up was a cinch
So far so good ...it is fast . I needed new everything including a keyboard (which is a nice one). Everything was self explanatory. Machine takes you through set up steps with ease . Was a good buy with a great price. So, onward and upward and away

Perfect Size and Weight
It's the ideal balance of screen size and portability. Light enough to carry anywhere but large enough to be productive.
