and a way to

boost your iPhone's meager battery life.

It's fair to say that Jay Goldman, AKA Mr. Mobile, likes the Nexus One hardware on the whole. However, great hardware is nothing without sweet software to take advantage of it. Jay continues his

in-depth look at the Nexus One, AKA Google Phone

with a look at Android 2.1 running on the device.

Jay Goldman takes a good hard look at the Nexus One, better known to some as the

Google Phone

. He finds a handset that feels great to hold and whose screen is a sight to behold. However, after having touched more than his fair share of mobile phones, he finds a few gotchas that anyone

looking to buy the Nexus One

should consider.

The iPhone doesn't have a radio tuner. Chances are good you haven't missed it. Old school radio is just so boring, commercial-laden and repetitive. Mr. Mobile turns his attentions to the skies, pulling down extraterrestrial

radio on his iPhone

with the help of the

XM and Sirius satellite radio apps for iPhone

.

In among the ill fitting, boring and otherwise useless iPhone cases are some shining stars. iFrogz standard Luxe cases and customizable Luxe cases are an example. These cases have a great feel, fit snugly over your iPhone 3G or 3GS, come with a screen protector and keep your phone protected in your pocket.

FoxPop is an interesting idea: it uses the microphone on your iPhone (or Windows or Mac laptop) to sync up with select FoxPop enabled DVD movies. Launch the app, it'll listen to the movie's soundtrack and pop up interesting facts, quizes, bonuses and extras on your screen. Currently, there aren't a lot of movies using the technology, but it's fair to say Mr. Mobile is impressed. Now, he' waiting for the next round of FoxPop enabled titles to hit his local DVD retailer's shelves.

Laptops have one Achilles' heel. The battery. MacBooks, for all their good looks and smug owners, are not immune. In fact, with the non user-replaceable batteries of recent MacBook laptops, they suffer more than most despite their impressive battery life. HyperMac's 100Wh battery pack for MacBook provides up to 12 hours of extra battery life to your MacBook.

Samsung's latest semi-smartphone, the Samsung Forever (SGH-A886) smartphone, has found its way into Jay Goldman, AKA Mr. Mobile's hands. He takes a good look at the phone and offers his full review. Aside from some design flaws and a justified annoyance at Samsung's choice to go with a proprietary accessory and charging port, it looks like a decent bet for anyone seeking some smartphone features without the smartphone sticker shock.
