I am looking to purchase a Tablet soon to use at work. Currently I am using a 2003 Toshiba Pocket PC to keep track of clients, tasks and notes along with holding blue prints digitally that I can edit in the field. I convert the DWGs to jpegs and use a simple program to edit the jpegs. I'd love to do this with an Ipad but I want to make sure it can handle the images. Some of the jpegs I have are 5000x3000 pixels... files size is typically small, around 3M or so. They don't have to be jpegs but they do need to be usable on a PC. SO basically I need to be able to open a jpeg in a simple (complex would work to) drawing program, scribble some notes or changes on it then resave it to a jpeg format. If they had Photoshop on the Ipad I'd love it but I think it would overwhelm my work associate that will also be using it. Many times I receive the prints in e-mails and the blue print is a PDF. I am assuming that the Ipad can read a PDF. Can it edit them? The only reason I am concerned at all is because I was reading a review somewhere that said the Ipad can't save images over certain sizes. I find myself never knowing who to trust since some ppl dist products just because they don't like apple.
