Recently, Sony announced that they were killing the 3.5-inch floppy disk. Which is fine, as far as we’re concerned. Macs haven’t used floppy disks in well over a decade, and with the internet, who needs ’em? But sometimes you just need to move files from point A to point B with a minimum of fuss, which is where the USB flash drive comes in. Plug it into your Mac, copy some files, plug it into another Mac--boom! File transfer done. While we usually use flash drives to move images, Word docs, and maybe a few ripped MP3s between machines, Kingston’s new Data Traveler 310 is made to carry a lot more--256 gigabytes, to be exact.

Zinio's multiplatform reader -- which lets you download digital magazines and view them on numerous devices, including iPhone and Mac -- expands to iPad in a stellar app, delivering hundreds of top publications with single issue and subscription purchases. At launch, the Zinio app displayed a few frustrating stumbles, including slow-loading pages and blurry text when zooming. Luckily, numerous post-release updates have largely addressed these quibbles, making for a worthwhile reading experience on the iPad.

Twittelator's edge among the current crop of unofficial iPad Twitter apps is its large feature set. While most users will be fine with the standard array of tweets from those you follow, mentions, and direct messages, Twittelator also includes a large number of themed channels (like sports and politics), which spotlight top tweeters in several smaller categories. You can also set up your own lists of Twitter users, should you want to create your own personal channels instead of reading one big feed.
