Surface pro 3 i3 version?

I'm considering getting the i3 version of the surface pro 3 primarily for taking notes with he pen. The main issue is that I need my computer to last for a long time. I'm pre medical and I'll be in school for a long time. I need it to last for at least 6 years. Again it is mostly for notes, papers and light web browsing.

Let me know what you think. Thank you.
