Backpack
37signals’ Backpack is such a great product that I stopped paying for it.
I started off with a free account, but quickly found myself needing more pages. I signed up for the Basic plan, at $5 a month, and happily paid for the service from October 2005 until July 2007.
A combination of awesome new features—page dividers and the ability to move anything anywhere, even between pages—have enabled me to rearrange and consolidate my stuff onto just 5 pages, thus removing my need for the Basic plan.
Normally, when people cancel their subscription for a service, it’s because they’re dissatisfied with what they’re getting for their money. I think it’s pretty neat that, in my case, that couldn’t be more untrue.
