Hi guys; I found my old iPad 3 gen this week, and I was thinking about make it a fancy note keep and PDF reader for meetings and my courses. So I was searching for the best pen compatible with this old device and came up with a good deal for a Wacom Intuos Stylus 2. What you guys think about it? Does it worth spend about 50 bucks in the pen? This old iPad can at least generate some notes and read PDF or .PPT ? Thanks so much in advance.
