Part of my job is to check out what people are saying online about free StuffIt Expander and StuffIt Deluxe.
The best I can figure there are people in three different camps: the ones that use free StuffIt Expander, the ones who love StuffIt Deluxe and use it for everything, and the ones who expend a lot of energy actively despising the format because it's been around for so long.
I'm not going to pretend to understand why it's a bad thing to have been around in the software industry for so long, but as a friend of mine once said, "There will always be haters."
"They've made a great tool for IT and Business purposes; Its safe, secure, and very easy to use. I recommend this if you are regularly sending files out. The new Stuffit comes with new optimized features for WAV, TIF, PNG, BMP, and MS office docs. Stuffit is going to have to become a standard in the future..."
I tend to agree. Not that I'm biased or anything.
