The ASUS VivoBook E203NA-YS02 / E203NA-YS03 is a very affordable mini-laptop. With a price of around $200, the E203NA-YS02 / E203NA-YS03 offers basic performance and a small 11.6-inch display in a slim and “featherweight” package made of plastics. The 2.2 pound notebook with a 0.7″ thin profile packs the Intel dual-core Celeron N3350 2.4 GHz processor, 4GB of DDR3 RAM, and 64GB of EMMC internal storage with “app-based” Windows 10 S operating system installed.
The Intel Celeron N3350 is an entry-level laptop processor. It is suitable only for the usual non-demanding PC tasks like web browsing with a few browser tabs opened, work in office-type productivity applications, or movie playback. The included RAM size of 4GB is the minimum on today’s notebook market, but it’s large enough for moderate multi-tasking with a couple of programs running simultaneously. As for 64GB of internal eMMC storage, it is quite limited by modern notebook standards, but you can expand it using laptop’s microSD card reader. The display of the ASUS VivoBook E203NA-YS02 / E203NA-YS03 is a common budget-class 11.6″ panel with HD 1366-by-768-pixel resolution and narrow “TN” viewing angles. The included battery provides a decent capacity of 38 WHr, which is claimed to deliver “up to 10 hours” of battery life.
As for Windows 10 S OS version, it’s worth noting that 10 S runs only Windows Store apps, not the traditional Windows programs. To run old-school programs like Chrome web browser, Photoshop etc, you’ll have to upgrade 10 S to full-blown Windows 10. Microsoft says Windows 10 S is upgradeable to full Windows 10 (Pro) free of charge through March 31st, 2018.
