I wonder where some people see the great adobe's products and why the hell, I can not see them.
This make me to believe that they compare the PhotoShop CS5 with Gimp and not with previews versions or with what the program should be.
I have been working with photoshop since... hm that's a long trip back, I think I started with version 3 or 4, in a PPC Macintosh 7200/75. I was but a kid by that time but I kept using photoshop and then I mastered it (if I can say that) while I entered college to take courses of graphics design and computer art.
I have noticed that there where a great evolution till version 8, or if you prefer the CS1. After that I really felt like the program is trying to be everything, without being good at anything at all.
It lost it's way to make things better and just started to add things.
After a little it made it up to CS5 of today, and what is that I see? A fat and ugly program with many functions that I will never use.
Now if this program was 3-4 programs with specific usage, and evolving relatively to what it is as a program, that could be better.
Same goes with the flash, from the program to the whole technology behind it. At start it was cool, it was way too forward from it's era. Then adobe bought macromedia and took the flash and didn't optimized it to make it better, just started to add things, and things and things.
We couldn't realize what a big fat program it became, because hardware evolution was giving us more and more power. No that the hardware is on it's slow down, and manufactures are worrying more about power efficiency, we realize that we don't need fat and big programs, but programs who will be optimized and can work efficiently on our hardware.
