My theory is there are a lot of folks that needlessly bought expensive ipads that sit around and collect dust when their kids aren't doodling on them. Finding out that Apple is bringing an app that could bring potential productivity to a bad investment got a lot of people excited. People will soon learn that another app was not the reason why they aren't using them.
All of that may be well and good, and yet I can't remotely get excited by an announcement that it's being ported from PC/laptop to iPad. Are professionals really going to be using iPads for this use case en masse? Was there a lot of people upset that they had to use a PC/laptop for this, and a lot of pent-up demand for an even more portable version?
It's hard to think of any platform port that would be amazing exciting news, let alone this one!
