I'm cheap and grad school just started for me, so I ordered the disc from Amazon. I can wait another couple of weeks; I'll barely have time to breathe breathe, any ways!
Lightroom 1.0 just came in a snazzy box, but there was no documentation and the disc was just in a plain-jane plastic box inside. I don't expect the boxed version of the upgrade from Amazon to be any different, but at least unlike my purchase of LR 1.0 from Adobe, I won't pay sales tax and I won't pay shipping. (Adobe nailed me on both when LR first came out.)
