Microsoft Office 365 comes included for one year, which includes 1TB of OneDrive online storage, Microsoft Office programs, and some Skype minutes each month. As a separate bonus, Asus is offering 500GB of online storage though WebStorage.
The rounded block design isn't flashy, and the matte finish will get very oily from kid's fingers, and cleaning it isn't a simple affair either - it will take more than just a cloth wipedown if you want it to look shiny and new again.
The keyboard can fold all the way back, allowing you to use it like a tablet. This is more comfortable when using it anywhere other than a desk (in bed, on the couch) as long as you don't need the keyboard.
The on-board Celeron N3050 processor accompanied by 2GB of RAM doesn't perform the best. In GeekBench (an overall test of the system's performance), it only scored 1560 which is below some of the 2000ish results from other laptops in this price range.
With only 32GB of eMMC storage, you'll quickly be searching for more storage. Thankfully there are ports which can help you achieve this - a SD card slot or USB key/removable hard drive are your best options unless you prefer cloud storage.
Working on it for long periods of time becomes a pain and it is hard to make use of tiling window managers that place applications side-by-side. Instead, you are forced to separate your applications into work-spaces or tabs and switch between them that way.
The 1.33GHz Atom Z3735F accompanied by 2GB of RAM is enough for light tasks to run smoothly side-by-side. It scores 2195 on GeekBench 3. It has slow data transfer speeds (31MB/s), and very slow at crunching data (matching up 20,000 names and addresses in OpenOffice took over 22 minutes).
While in use, the top remains very cool, however the bottom gets uncomfortably hot. As long as you use it on a desk you will be fine - not your lap (comfort reasons) or on soft surfaces (overheating reasons).
The S21e is for all intents and purposes a regular 'big person' laptop. It depends on the kid, but some kids around 12-14 start wanting to become an adult, and this laptop will be perfect for those who aren't into super flashy 'childish' colors.
The 2.16GHz Celeron N2840 processor paired with 2GB of RAM provides lackluster performance. In Geekbench 3, it scored 1694 (below the HP Steam's 1804 score, also below the EeeBook X205TA's 2212 score). However, it performs admirably in OpenOffice testing - 25% faster than the EeeBook X205...
