It’s Courier clone week (also see The iPad app that will remind you of Microsoft's old Courier project)
“The tool Petschnigg and his company FiftyThree thought up is the aptly named Paper, designed exclusively for the iPad. It's essentially a blank slate of paper devoid of settings panels, menus, and adjustable line widths. If Paper looks familiar, it's probably because the team behind it had an interesting history: a handful of them spent several years at Microsoft, with a good chunk of that time focused on the Courier, a dual-screen, digital notebook which had the tech world salivating. That device and its software was very publicly killed by Microsoft, but you can see threads of it that survived in this new project.
Still, the FiftyThree team is reluctant to admit that there's Courier DNA in Paper, perhaps only because the project they so passionately incubated never came to be. Whatever the case is, the humanistic sensibilities that made the Courier so attractive are very much present in this app. And that’s a very good thing.”
