Here is CS4 bèta running You can't download it yet though I think. I never used CS3 because it won't install on my PC, so I use CS2 and I'm statisfied about it.
According to http://www.adobe.com/products/photoshop/family/?promoid=BPDEK there are 2 editions: Photoshop CS3 & Adobe Photoshop CS3 Extended
Stonehenge is a weird title I believe.... gets the feeling they downgraded their product to stone age lol Anyhow I'm stuck on CS2.. It's the best photoshop version so far.
Iam using only photoshop cs2& i have cs3 but its not suitable for me to work so i use only cs2 its very convenient to work in cs2 and give the link where can i get new version for free not for money.
cs4 is not released yet (read my article => http://www.photoshoptutorial.tv/adobe-photoshop-cs4-leaked/) Currently, I'm running cs3 on my pc really better then cs2...
cs4 is realeased but its the beta version but you can only download cs4 illegally but i saw a video on youtube and it seems almost the same as cs3
lol kind of but it'S also good for beginners because it'S not that expensive an got all the important photoshop features. the rest you might miss is stuff you kind of don't need working with cs3 so far and I'm getting along with it pretty good but for me there is no big difference to the cs2 version i had before.
