I’ve logged more than 20 years of Macintosh use, along with a quarter-century of computer industry journalism for enterprise users. That’s what’s got me testing, applauding, complaining and tracking what’s become of the Apple user experience, from those days of the Mac SE and 9-inch screens to an iPod Touch that lets me read my e-mail and the New York Times. I’ll keep an eye on how your favorite vendor is changing, improving or economizing its offerings, especially for the business owner — independents up to enterprises — plus point out the gems of companies that keep our community innovative and growing.
