Jonathan Takiff: Go back to school with cool gadgets

Today, nothing says "leave me alone I'm studying" (or, "I'm cool") like a serious set of headphones. The Audio Technica ATH-A900 (about $180) boasts prograde aluminum earcups, high-end speaker drivers and a unique 3D Wing Support structure - stabilizers that float below the headband, balancing weight and reducing pressure around ears.

MORE MUSTS: Trying to make do with just a tablet computer and no laptop? Writing becomes way easier on a wireless (Bluetooth) Logitech Tablet Keyboard for iPad ($69.99). The keys are full size, while the device's travel case doubles as a tablet stand.

If toting a laptop plus an external mouse, how are you protecting the latter? Smartfish makes a handy dandy Mouse Pad Travel Pouch ($15) that zips up around the little bugger, then opens into a full-size mouse pad.

The good folks at Griffin make scores of smart accessories. Their TechSafe Cable Lock System ($30) secures laptops, notebooks or netbooks against theft. Griffin's PowerBlock Reserve is a small wall charger for iPhone or iPads with a "quick 1 amp charge" function. Plus, it features a magnetically attached (!) backup battery that you pull off quickly and plug into your iProduct when needed. $50 at the Apple store.
