Hi. I currently have a 13.3" laptop (16:9 aspect ratio) which I use for Excel a lot, and am considering getting the SP3. The Surface Pro 3 claims that because of the 3:2 aspect ratio, its 12-inch screen can actually display the same content as a 13.3-inch panel with a 16:10 ratio. I don't completely get that logic but was wondering if this holds true for viewing spreadsheets. For those of you who use the SP3 with Excel, what has been your experience? Is the screen too small or does it work fine? Thanks.
