Adobe Labs released the first Beta of Photoshop CS3, optimized for Intel processors, yesterday. I downloaded it as soon as I got settled in NYC and I must say I am loving the improvements. In addition to the tremendous speed gains, the interface is slightly tweaked and seems a lot more streamlined. There is also a fancy fade effect when you change application focus to and from Photoshop.
Adobe also changed the icon to a blue square with "Ps" in it, like they made it just for me. I think I will definitely buy CS3 when it comes out - the cheaper, education version of course.
