Need New Computer

Hi, My name is C.A. Monk. I write, co-letter and promote a comic called StarHammer. Recently my computer gave up on me after an accident with the battery. It now no longer holds any data or can hold a charge. But now I need to replace it with another Surface, since that's my computer of choice. I'm hoping not to run into this issue again anytime soon. So I'd like to get one with a better battery, better memory and better storage. And I can keep lettering and keep making the promotions for the comic.
