Here&#x27;s a video [1] by a math grad student showing how he uses a Surface Pro with OneNote for his math note taking, annotating papers, and stuff like that.<p>It can search in handwritten notes, and can convert them to text (including converting handwritten math).<p>I don&#x27;t do enough math writing or note taking to justify the cost of a Surface Pro, so don&#x27;t personally know if it really works as well as it appears to in the video.<p>[1] <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=C7OROShRVzQ" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=C7OROShRVzQ</a>
