Might be traveling, and I want to come up with a lightweight solution to upload and and process keepers on the road for a photoblog I am putting together. I currently only have a desktop at home, and I am thinking about getting either a laptop or an IPad. There are other factors at play, but the ability edit and upload photos on the road efficiently will likely play a large part in the decision making process. I would really like to be able to decide upon the iPad, because I like the form factor and price. But I don't want to feel like I should have gone with a laptop. I don't need much in the way of processing, but I would like to be able to easily crop, adjust levels, and do some of the basic stuff. does anyone here utilize an iPad for anything like this? Which apps if any?
