Well sports fans, I finally made the decision to delete CS6 Beta from my computer and return to my trusty CS5 Extended. I'm still running XP (gasp) on my computer and a good chunk of the features on CS6 aren't available for this OS. The 3D section is entirely gone, plus other various features.
The replace and fill worked to a certain extent but it still needs you to do some tweaking with the healing brush to really make it effective. You can actually do this via a few step's manually, but the replace fill does some sort of macro to make this function automatic The blur tools were sort of fun, but nothing that I couldn't live without. All in all, CS6 is nice. but not worth it as an upgrade because of the issues I previously mentioned. I use CS5 Extended virtually everyday and for my money, it still does an amazing job.
If you ever venture outside of the XP world, give CS6 another shot. I think you'll be quite impressed with the GPU enhanced features. In terms of the "replace and fill" feature, which I'm assuming you're referring to Content-Aware, it'll never be perfect. With some images, you'll get great results, while others will require a few more steps. It's a great starting point though!
Speaking of Win 8, I'll likely delete that from my computer and put XP back! Yep. I have certain HW/SW stuff that won't run onWin7, and from the looks of it, my printer (Epson 3800) may not run on Win 8. Between the two, it may be $2K just to be able to run in Win 8.
So, XP, full speed ahead (dual boot; I can't run many other things well on XP)
I can't begin to imagine trying to keep things straight on a system that's dual-booted. Have you considered using virtualization on a host Windows 7 system to run the things you just can't run in Windows 7? That seems to me a better way to do it.
