Currently using an old MacBook Pro. The battery is bad, I mostly use it plugged in. As of yesterday, have developed colored vertical lines across display and must now use laptop hooked up to TV (where lines don't appear). I did not want to put a battery in and certainly can't justify a new display so looking at new M1 MacBook Pros. Thought by upgrading from 8 GB to 16 and bumping storage up to the 512 option would future proof my purchase. However, that configuration will not be delivered until 12/30. Not sure if I can continue to use current device - if lines worsen won't be able to see where to sign in, etc... Perhaps should consider the 8GB/512 option - any recommendations/thoughts - thank you in advance.
