Lotus 1-2-3 similarly benefited sales of the IBM PC. Others also developed software, such as EasyWriter, for the Apple II first because of its increasing sales. BYTE wrote in 1980, 'VisiCalc is the first program available on a microcomputer that has been responsible for sales of entire systems', and Creative Computing 's VisiCalc review is subtitled 'reason enough for owning a computer'. Because it was not released for other computers for 12 months, people spent US$100 (equivalent to $400 in 2022) for the software first, then $2,000 to $10,000 on the requisite Apple II.

In these cases, the qualification process takes longer than usual. Some of our surveys have quite a few screening questions at the beginning because they are looking for a very specific group of people. We're sorry you're experiencing difficulties. I won’t be doing any survey anymore, because they let fraudulent one in the bunch.

I’ve tried to report the problem to the service, but they don’t see a problem with that. Lately, I’ve been having problems with their survey, because they do the selective processes but let you do the survey, and they don’t pay you at the end, because they say they have reached the number of participants for your group. You get a survey and you answer a couple questions to know if you can do the survey based on the criteria they’re looking for, and if you’re not selected they still give you 50 points to rewards you.

I’ve started to do survey on Leo a couple months ago and it was really well done.
