Since I attached my iPad to a keyboard I have found a subtle need to work differently with the touch screen. Being at an upright angle makes the interaction with my hand different, less natural and often less comfortable.
Coincidentally I got for Christmas a set of biros with a soft nobby bulge on the top which would act as a stylus on a touch screen. At the time I smiled but thought 'not going to use these'.
They have proved to be a constant companion. Reading on the iPad, which I do a lot, is easier when I can scroll and highlight with the stylus. Who'd have thought! Also I found that taking an actual pen to meetings helps with those awkward moments when people expect you to have a pen to sign into the meeting or they hand out a last minute paper and you need to make some notes.
The pen has become a dual use, modern workhorse. Bring on your paper or your tablet, the pen is up to it. When I went to a meeting and the give away biros also acted as a stylus it was official. The pen plus stylus is now a thing.
The pen is dead, long live the pen.
