Photoshop CS3 Beta out now.

1. It flies on Intel Macs.
2. Refine Edges is great.
3. Smart Filters are great too, though I would have preferred them to work like Adjustment Layers so they could be applied to more than one layer at once.
4. Interface is much improved.
5. The new Curves dialog, with histograms, is fantastic.
6. Quick Selection is destined to be abused like the Magic Wand, but at least it’s an improvement.

Oh, and the CS2 -> CS3 serial number thingy isn’t working yet, but the trial works for 30 days. Note that Adobe have taken away the links to this for now, perhaps to change some serious bug, perhaps to reduce the free trial usage to 2 days as previously stated. So grab it now.
