LogTen Pro is Awesome! I just uploaded 14 years of flying from an Excel spreadsheet. The customer service is awesome. Very nice tools to figure out all the different types of hours totals that airlines want for applications.

I have a 5 year old, used Macbook Pro w/Lion that I use it on. Works great! The only down side is I will have to pay additional money to add it to my iPad. I still think it's worth it!
