I am right now downloading the Photoshop CS3 Beta to the MacBook Pro. This is a HUGE 684MB file and I am 5 minutes into the 22 minutes or so the download should take although I am noticing the throughput slowing. i wonder how many copies will be downloaded today? Talk about bandwidth!
I will try it on the Dual 2.0 G5 as well but CS2 works pretty well there I am really interested in the speed increase on the MacBook with the Intel processors.
More of a report when I get use it some.
Note you will need a valid copy of a CS2 serial number.
