It seems Lexmark has done the competition one better, two better actually, with three new AIOs with similar web-connect and touchscreen characteristics, though no mention of a comparable iPhone-inspired "apps store" or the APIs and developer program that support that. From the release:
The new line includes three Web-connected touch screen AIOs with Lexmark's myTouch capacitive 4.3" touch screen technology. The touch screen AIOs will be available at competitive price points ranging from $199 to $399.
Lexmark's myTouch with SmartSolutions technology is an innovative, easy to use approach to user interfaces and includes easy-to-read graphical icons for basic AIO functions and "as needed" navigation for a more user-friendly experience.
