Until now, Surface Pro had no competition in this specific niche, except some Android devices that are likely inferior in hardware and app support. Now it does. Every app for iPad is designed for touch from the start, including the Photoshop port etc., meaning the touch experience for artistry will be better; the question is whether the inability to switch to a trackpad afterward for more precise editing and more complex functionality will outweigh this.

Photoshop port for iOS? Where? All I can see are toy-touch-up apps using the "Photoshop" name-brand. But now way a Photoshop port.
