Ok. This is me, Will. I've got an ipad2 and use it for work and entertainment.
My main uses are diary, notes, and loading papers for meetings and reference, for which I use Pages. This is not only saving paper but means I do not have to carry several books etc when visiting people.
I also use iBooks, Kindle and I am building up a small classical music collection.
I hope to develop using the ipad for presentations when linked to a projector.
I use the internet when at home and access emails when away for a few days and in wifi hotspots.
I chose not to buy the 3G version as I do not need constant internet access.
