Many photography editors rely on Photoshop, image editing software, to do their daily jobs. A future version of this piece of software may prove to be troublesome for people with computers with 64 Bit processors. Although Adobe does plan to release future versions of Photshop with support for 64 Bit processors, this will not be the first edition to do so.
This future version does have features that many users have been waiting for, however. For example, owners of Intel Macs will be able to run this application without using Rosetta (A PowerPC imitating application), but completely native, and much faster. This is one of the main reasons many Mac users will buy this software.
Although Macs do not currently support 64 Bit applications, and Windows XP, only has a very limited capability, both Mac OS X and Windows' operating systems will soon be updated to support 64 Bit fully (Mac OS X 10.5 Leopard and Windows Vista), and at that point, Adobe will be behind.
