Over time I added 8 GB RAM, 256 GB 2.5" SSD and an AC card. Mine has no touch screen. It is a TravelMate B115 series. If you can find an external monitor/keyboard while you are traveling, it is pretty good.
This current B117 model has a Celeron for $186, is more like mine https://www.amazon.com/Acer-Travelm...01BBXPNYM/ref=cm_cr_arp_d_product_top?ie=UTF8 there was more selection in Europe from Acer in this lowcost range. Looks like a pretty lowgrade (academic) Windows license which you don't need. But you need to check if the RAM/SSD/wifi is upgradeable--mine was.
Ignore the reviews: the stock specification is indeed useless--it all depends on the upgrades.
