I updated Adobe Photoshop CS 2 to CS 3 finally I have been waiting for this for a long time and it was a brilliant upgrade.
Finally they make it easy to see your design, this is my favorite feature in Photoshop, and basically as you have your panels open you can fix them down so your picture will not be able to go under the panels. This is brilliant in CS2 I was always moving the tools and layer panels.
For the money it costs to upgrade I can’t say it was worth it, in GBP its around £100 USD you can find it at $200 considering I brought the original for whopping $600 that is a lot and it doesn’t really earn me much back, brilliant for a hobby though.
Overall if you have CS 2 I say buy Adobe Photoshop CS3, I’ve always preached adobe software due to the fact they are brilliant!
I believe you can also use Adobe Photoshop on a USB flash drive using something like thinstall, I’ve also seen it on many torrent sites. Which I believe is illegal.
