Helena and Cinda, this may be relevant to your interests. I don't know if you guys know about it (or want to download it, or even able to install it :( ), but the beta version of Photoshop CS6 is available for download free. From what I've gleaned from other places, "the beta will eventually expire, though at the moment there doesn’t seem to be a set date for that to happen". So it's free and it's new, and if you can use it you might want to download and try it (I don't know what your situation is). Just be aware that it is a beta product and it can still be buggy.
Download Photoshop CS6 beta from here.
