I need some information on this one.
Can anyone tell me whether this Adobe Photoshop CS4 has the same features like the original one?

There is already Adobe Photoshop CS5 (http://www.adobe.com/products/photoshop/photoshop/whatsnew/index.html?segment=design).

Yeah, I know that. The point of my question is, are the portable ones the same than the unportable ones?
Does the portable ones has disadvantages?
