As a tech startup lawyer on the go I use my iPad constantly for business productivity. This list reflects the document-intensive nature of my work Evernote - note-taking organizational tool and cloud storage for all kinds of documents; cross-platform (iPad iPhone Androidputer) EgretList - handy ingenious to-do list app that runs on top of Evernote TimeMaster - client time tracking and billing Expensify - track business expenses generate expense reports iAnnotate - PDF reading review annotation ReaddleDocs - more document review; both good choices PrintBureau - amazingly versatile app to print wirelessly just about anywhere Penultimate - handwritten notes diagrams Air Sharing - easy file sharing over WiFi Air Display - turns iPad into a wireless external monitor for the Mac; pretty useful if you have an 11 or 13 screen! Bloomberg - financial markets and news Calculator XL - for obvious reasons when a spreadsheet would be overkill Night Stand - turns iPad into a digital alarm clock; one less thing to pack when traveling! FlightTracker Pro - flight tracking with live status updates; syncs with TripIt Flipboard - bestbined reader for Twitter Facebook Google Reader etc. Offline Pages - like it sounds; cache Web pages read them later on the plane without any Internet connection Angry Birds - for when there's not quite enough time to actually be productive!
