Yup, I signed the petition.  Last I saw they had over 30,000 signatures.  There's been quite an ongoing protest in Adobe's forums but they don't seem to care.

I have GIMP installed and it does most of what Photoshop CS5.5 does, it just can't do the special effects in layers, nor can it work with 3D models for painting textures.  If I can find something to do those two things, I'm set.
