Howdy all.
I'm looking at upgrading from photoshop CS to either CS3 or lightroom 2. Just wondering what the main differences are between the 'educational' versions vs. the 'full versions'???

Is it purely licencing? i.e. I shouldn't use it for commercial purposes? or are there any other differences to the programs?

Also, I'm looking at CS3 as I can get it a fair bit cheaper then CS4, I presume there's not a whole lot of difference between the two? Anyone want to convince me otherwise? or push me towards lightroom 2? I think I can get CS3 a fair bit cheaper than lightroom 2 as well...

ta!
