One thing that people always seem to think that an IPAD can be a replacement for a laptop. It can't. Sorry. Never will. You can't run GIS, you can't run design software programs, or have enough processing power at this point to really replace a laptop/desk top.
On the other hand, the IPAD is handy as a task, or notepad, but not in the way 95% of the population think it should be done with a standard keyboard set-up. To really get a good bang out of the ipad, transform it to a supreme organizer/note taker is to by a
stylus pen, and then use iannotate and ghostwriter notes apps and go from there. Truly, this replaced pen/pad and gives you a great way to organize thoughts, ideas and take notes, email them, share them in the cloud and provide a good digital record.
My boss and I have been doing this for the last two years. He has completely transitioned out pen and paper and relies solely on his ipad. I can't break the habitat, but I am getting there.
This was done on the ipad using the stylus pen, i annotate for the mark-ups in PDF and ghostwriter for the notes section. Yes it takes practice to get the writing on the ipad, but after about an hour or so of using it, you get the feel on how to write on it.
