I would like a relatively thin 11 inch Windows laptop with a decent display. Hopefully I would be able to upgrade the ram to at least 8gb and a 128gb SSD. Is there anything like this available used on eBay? I'm currently looking at the GEO book 1m.
I would not get new Celeron laptop even if it was given free to me. I don't expect this particular one to come with upgradeable memory, or SATA drive. I've seen plenty of these made with phone motherboard, and slapped batteries. Stick to known brands if you want "decent display", "upgradeable RAM", and SSD option.
