I still remember cringing the day I finally had to move my parents business off CA Simply Accounting for DOS. There was definately a learning curve for the text based app but it took far fewer steps to actually input the data and print off cheques, etc. 15 years of accounting easily fit on a 1.44MB floppy disk. Now, it's a monster database with a terrible UI. In subsequent years Simply has become anything but simple and I cringe at the thought of giving in and moving to the cloud. Ledger doesn't look like a great fit for business though, and accountants want data from accounting packages they know. Quite a racket.
