adobe has always been overpriced. it's part of their mystique. Like buying a mac. You pay more for the priviledge of saying "I own a Mac." Same thing with Adobe Products. The only reason I use Premiere Pro right now is because I got a free copy for a class I teach on it.
Not really. If you do pro graphics, you'll think Photoshop is downright cheap, especially since a mistake due to poor separations or color management (two things Photoshop is excellent at) will cost you more than Photoshop did.
Also, if you've been used to using Quark XPress, you'll love the deal you get on InDesign.
