- The latest Compact Pro, for example, slightly improved the compression
- and nearly doubled speed (both within a few percent of StuffIt Lite,
- with the difference admittedly in favor of StuffIt), and the files
- can still be extracted by the original Compactor.

- Granted, but sometimes I want to compress files, also. The key I got
- when I registered Compactor unlocks the latest distributed Compact Pro.
- StuffIt, on the other hand, keeps asking me for money.
-
- And, unfortunately, there's a synergistic obsolescence: Compact Pro
- takes 96K of disk space and 504K suggested application memory.
- When I registered StuffIt 1.5.1 Aladdin sent me StuffIt Classic. I
- installed it. File after file after filter. I just didn't have
- room for it on my SE with 20M internal -- it became shelfware.
-
- As I see it, Compact Pro is cheaper, smaller, and simpler than StuffIt.
- I could live happily without StuffIt, and would if I had the choice.
- A few percent in performance isn't worth the money and disk space.
- But, yes, I am grateful for the free StuffIt Expander.
-
- YMMV
