Are older softwares better than newer ones?

with new versions of photoshop and flash coming out every 2 months, you have got to ask yourself, "Are the newer versions worth my money? Do I really need the newer versions when I have got used to the older ones?".

I recently switched back to photoshop 7 and I must say I have been very efficient with it.I found myself at home with photoshop with 7. The UI is simple and intuitive, and it doesnt take a genius to make out what the "accented edges" filter does.

I have always been a critic of new software, and have always advocated the older ones. Photoshop 7 continues to be the most productive tool in Adobes galleria, as I am told. This goes for windows XP too! How many times have you thought "Man, it really sucks that vista is running so slow on my 2 week old PC" ?

What is the need for you to use newer software when you're god darned efficient with the previous one?
