I use 2. I bought elements 5... it rocks.. I liked it so much I couldn't wait for my first cs software. I picked up CS3, then I went to the local bookstore and picked up about 5 books for CS3. Read them all and now use them for reference. Now I am hooked on CS3.. yes I tried CS4... I prefer CS3 still.. it does everything I need...and I still don't know everything about it. But... I miss my elements.. when I installed CS3 it overwrote my elements... so I had to add elements again after CS3's installation. I do a lot of baby, kids and weddings. I use the elements for borders, edges and adjusting skin tone in my portraits. Elements has automated those and I find them VERY useful.. and my creativity never ceases... Why not both?
