Is bluetooth on a laptop really necessary?
Screen size is mainly the only difference. There are some than have better resolutions, etc. but that’s getting really detailed. Not that important, unless you have bug for that. Bluetooth isn’t necessary. It’s only a luxury. You’d probably find yourself never using it. You can use it for a wireless mouse, but there are ones just as good for a lot cheaper than just use a small wireless device to plug in a USB port and you’ll still have a wireless mouse. As for graphics system, if you’re not going to play games, go for the basic. It’ll save you money.
