Mine came with 1TB NVMe but that's all I can do with it. I had the same model before and opened it up to see what was in it. I couldn't add an extra stick if I wanted to. Can't complain. The price was right. Based on what NVMe costs now it would be like buying the NVMe and a replacement keyboard. Specs read as follows:
Laptop 16 inch, Windows 11 Pro, 12th-gen N95, Quad Core, Up to 3.4GHz, 16GB DDR5 RAM, 1TB PCIe NVME SSD, 16" FHD IPS 1920x1200, 2.0MP, 2.4G+5G WiFi, BT 5.0, HDMI, RJ45, Type C, Gray
Cost around $350 US. Not surprised to see it's no longer available for sale. I share the same sentiments as you with respect to laptops. I never really could adapt to those keyboards and I still use a mini mouse because touch pads are so impractical. Gave the fancy Dell with the touch screen to my daughter because I couldn't adapt to that either. lol Just not a laptop kinda guy. Ironically, it's the only PC I own that uses DDR5 RAM.
