If you look at well-prepared documents on your display vs. on a new iPad, you will be able to see a difference (provided your eyesight is OK). The new MBP with high-res display has around 130 PPI, significantly more than your display. The new iPad has twice that. So now take a look at the page numbered 20 in this PDF: http://www.math.princeton.edu/~nelson/books/bmotion.pdf http://www.math.princeton.edu/~nelson/books/bmotion.pdf (starts with "and for each t > 0"). The difference between the MBP and the iPad is night and day. The italics, symbols, and math in the document render much more nicely on the iPad. Take a look at the parentheses and the script letters in particular. (I did this experiment.) Incidentally, the T220 is no longer available new.
