I started using one of the first versions of Magic almost 30 years ago. They've evolved since then, and xpa is the latest iteration. 

I have used this solution for eight years.

I've been using Magic products and their programming tool for over 25 years. The xpa version only came out a few years ago, but that's just another release. It has had different names throughout the years. Now it's xpa, before that it was uniPasS, before that it was eDeveloper, and before that it was just Magic. I've been using all of these products from the very beginning.

I have been using the Magic xpa Application Platform for approximately 11 years.

I have been using the latest version of Magic xpa Application Platform for around two years, but an earlier version since the mid-nineties. 

I've worked with the Magic xpa Application Platform since it was introduced in 1990 or 1991.
