Photoshop sucks. Adobe sucks. Everyone gets a kick out of pirating Adobe software, just like how everyone does with each pirated copy of Microsoft software.
No 64-bit Photoshop for Mac till CS5? You know what, Adobe? You can keep your CS5 for yourself and your Microsoft bitches.
Photoshop will become irrelevant in 2 years. Die. Photoshop. Die Adobe. Die Lightroom. Die.
