I will very soon be in the market for a new surface pro 4 and I need to know how well the 4 GB performs with Windows 10. I plan to primarily use the SP4 in tablet mode (which I assume will be excellent with 4 GB of RAM) but really want to know when using it in PC mode how well it performs. 1. I was thinking of using duOS android emulator and am worried about the RAM for that. 2. Also how is light gaming with the 4 GB configuration? 3. Performance using the Xbox app to stream Xbox one games to the SP4? I assume this will be fine but wanted to check. If anyone can address this I would be most grateful. My alternative is to buy a SP3 with i7 8 GB RAM. With the new touch type cover and Pen. Thanks!
