I’d be all over Adobe’s $10/month LR & PS deal, but Lightroom customers (longterm ones included) are just second-class citizens in Adobeland.
I bought LR when Adobe actually made it a relatively comparable price to the US down here in Australia a couple of years ago, and I’m now on my third version. But Photoshop is insanely overpriced (Australia Tax, simply due to geographic location) compared to the US price, despite downloading the same 0s and 1s off the same server.
As you can tell, I’m not terribly surprised by this attitude to LR customers, given Adobe’s attitude to almost all of its customers except its core US big-business base.
