Firstly....this is not a thread about whether an iPad is worth it, so please keep to the thread topic!

I thought it would be useful to share apps that are good value, and am particularly interested in the photography ones (obviously )
I am interested in the portfolio ones, as they are quite expensive....I was hoping to hear from anyone that uses them to find out how they perform.

Having looked at a previous threads, Rick suggested Office HD, JM Tran uses Poses Professional, Adillucca: Guardian Eyewitness and Reuters Galleries.....both these are free and download news images from around the world...some examples just for starters.
