1. must be 100% compatible with Win 10
2. extremely stable, basically problem free (dislike things like RMA ...)
3. reasonable speed
4. 3 years of warranty is good enough
5. price level ... subject to the above requirements
So, point 1 and 2 are the most important requirements.
ASUS VivoPC : celeron 1007U (pretty slow) with 8GB ram and 500GB hdd. And there is only 1 hdd slot.
Things like Crucial MX200, Sandisk Extreme Pro, etc. ... would be the best ?
