Adobe Photoshop can be yours for $35 per month if you agree to rent it for 12 months, or $49 per month if you require its services for a shorter period. Dreamweaver can be had for even cheaper, at just $19 per month. The entire Master Collection is still rather expensive, though, at $125 per month.
Today, Adobe also ushered in the release of Creative Suite 5.5, and simultaneously upped its release cycle from 18 months to 24 months. This means, if you rent Photoshop for two years, it's actually the same cost as buying it outright. There's no rent-to-own option, though -- so you wouldn't have access to the cheaper upgrade price once Creative Suite 6 rolls around next year. Still, if you need access to Photoshop, After Effects or Premiere for a one-time project, the new rental scheme could be exactly what you're looking for.
In other news, Adobe has announced that it will be launching three rather exciting iPad apps that work in conjunction with Photoshop: Eazel, Nav, and Color Lava. Eazel lets you five-finger paint on your iPad, and export the result into Photoshop; Nav acts as some kind of workspace, brush and menu extension, and the hopefully named Color Lava is a paint mixing palette. The apps are expected to appear in the App Store in the next 30 days.
