Question: is pen important, and if so, to about how much of the market. In the last few months there have been several threads about the surface and its pen function. Many of the respondents have cited pen input as a niche feature of no particular consequence. Yet there is significant market for ipad stylus's and almost all pc manufacturers provide a pen version of at least one of there hybrids or tablets. Also samsung has been very sucessful with pen models--although argueably not because of their pen function. I find the situation hard to assess. My intuition is that 1/4 to 1/3 of the market--including students, designers, engineers, sales, etc--could value a useable pen input. My other thought is that pen technology--although pretty good--might improve significantly over the next 5 years. Thoughts?
