I upgraded my laptop (my primary system) to a Mac Power Book Pro in February. I was previously using Photoshop CS2 on Windows XP. I now want to upgrade to CS4 but the cross-platform upgrade process for Adobe is so extremely complex and time consuming (wait for Monday - business day, minimum of 3-5 days shipping) that I am now investigating alternatives.
Does anyone have any suggestions for good alternatives (other than GIMP) to Photoshop CS4 on Windows?
