Styli for tablets seem to be a blossoming category, likely as a result of the Draw Something app from OMGPOP. Check out the stylii from Logiix, which makes a full line of these devices, even one with a built-in laser pointer ($40). They look good and work well. Prices start at about $20.

Waterfield, which makes all of its products in its San Francisco factory, just introduced CitySlicker, a MacBook Air case that’s very thin, yet provides excellent protection. There are models for both the 11-inch and 13-inch MacBook Air, each with pockets for the charger, mouse and files or magazines. Its interior is made from three layers of material: impact-resistant plastic, neoprene, and a soft padded liner. The exterior is constructed of ballistic nylon and leather. Prices range from $129 to $149.

Waterfield makes another mobile gadget that’s worth noting. It’s the iPhone Wallet, a small leather zipper case that holds currency, credit cards and an iPhone. A window on the front of the wallet lets you use your phone while in the case. Behind the phone is a divider that keeps the phone pressed up against the window and separates it from the cards and bills. It holds about 10 cards and 10 bills. ($39)

For the Home: Chargers & More

Kensington’s AbsolutePower portable charger is designed to simultaneously charge three different devices at the same time: your notebook computer, a smartphone and tablet, or a notebook and any two USB devices. It’s a significant engineering accomplishment in that it provides 100 watts from such a tiny, lightweight and attractive form factor. In fact, it’s smaller than most chargers that come with your notebook. It has a 2.1-amp capacity and comes with interchangeable tips for nearly all notebooks. Unfortunately, due to Apple’s unwillingness to license its magnetic connector, it doesn’t work with MacBooks. But charging three devices from one outlet is a real convenience. ($119.99)

The iTwin is an unusual looking gadget that synchronizes files between two computers without the need to use storage in the cloud, the method DropBox, SugarSync and other software uses. It looks like a memory stick, but has 2 USB connectors, one at either end. The stick, however, separates into two pieces, each with a connector. Plug the iTwin into your home computer. Drag and drop files into the iTwin window to share them. Take the other half of iTwin with you or snap it into your notebook computer.  You now have instant access to your shared files, from your notebook or any other online computer, no matter where it is, with greater security than using the cloud. ($100).

Expect to see lots more mobile devices come out this Summer and Fall. We’re likely to tablets from Google and Amazon, new iPads, many new notebooks and perhaps a phone from Facebook.
