Adobe Ink and Slide review: A software giant tries its hand at hardware:

Engadget

As big as Adobe is in the software space, the company only announced last spring that it planned to dive into hardware, starting with a cloud-connected stylus and a drafting ruler. The Ink and Slide, as they're called, are accessories that allow the company's creative-pro customers access to Adobe's Creative Cloud service on mobile devices. Now, the final versions are available in the US, and as you might expect, Adobe has a smattering of companion apps in tow for making the most out of what could otherwise be a dear $199 purchase. With hoards of more affordable styli to choose from, are Adobe's efforts really worth the premium? As is often the case, the answer's a bit more nuanced than a simple "yes" or "no."
