This is the only ultra-book I could find with a 64gb ssd, 4gb RAM, weighed only 2 pounds (actually 2.1) and cost $200.  If your expectations are reasonable (i.e. don't expect to find a large screen, don't expect to run intense programs or games) then I think you will be happy with this.The notebook comes with Windows 10S (not windows 10) which can be upgraded free and easily.  If the upgrade is not made, then you are limited to the programs/apps in windows' store which is not very comprehensive.  The only issue here is that the Windows 10 version the upgrade goes to is 64 bit (not 32) which has compatibility issues with some older programs.I found the eMMC disk drive to be fast, the computer boots in a few seconds.  There is a Micro SD slot.  256GB micro sd card is only around $25 and is immensely helpful in increasing available storage (buy a name brand only; i.e. microcenter, sandisk, pny, crucial, kingston, etc etc).  The internal eMMC drive or the RAM can not be upgraded.WiFi is strong, the screen is only 11.5" but is very bright and has very good resolution and color.  The USB ports are V 3.x.  The keyboard does not feel cramped or compromised in any way despite the small size of the notebook.  Too bad it does not have a trackpoint which would be very helpful in navigating more precisely on the small screen.I have only had this so far for a week so I can not comment on durability.  The card slot seems a bit flimsy.I have been unable to get anything near the "whole day" claim on a battery charge.  6 hours is about it but obviously that is still very good.Overall I believe this is a very good choice especially for this price range; this laptop is not much heavier than a tablet but is much more useful.  Also, Windows 10 is far more versatile than the Chrome OS, in my opinion anyway.
