I will hold on to my activation-free fully-offline Photoshop CS3 until the day Win32 finally dies. Still using it daily with an equally-old Wacom tablet to clean up all my flatbed scans :)
You can't compare Photoshop CS3 to the newer versions.
I've been using Photoshop since CS2, it's incredible how far it went. Of course if it does the job you need, then that's great. I use the latest version of Photoshop to cleanup family photos, and to design video games. In both cases it would take me much longer to do the same thing in CS3. Time is quite valuable, and Photoshop is cheaper than Netflix every month.
