Nokia's timing couldn't have been any better when the revised and enhanced U.S. version of its flagship N95 smartphone (the N95-3) went on sale last week-just days after the iPhone's 1.1.1 firmware update officially shut down third-party apps and rendered useless many iPhones that had been unlocked.

Here, we present a compilation of PopSci coverage of the season´s hottest tech- 60 pages of lust-worthy items, from a luxury amplifier that will please the most discerning audiophile to cutting-edge smartphones to household gizmos that will make everyday tasks easier. Get ready to drool.

If it´s a smartphone,
you bet. In 2004, virus writers released Cabir, the first proof-of-concept virus that could infect smartphones through

Forget AT&T and the like. The only phone company you need is Skype, which routes your calls over the Internet and, as of May 15, 2006, costs nothing for outgoing calls made by users in the U.S. and Canada. And now you can almost forget your cellphone provider too-with this new Voice over Internet Protocol (VoIP) gear, you can make calls using Skype (or Vonage, another VoIP provider) from just about anywhere.

But at last week's CTIA (Cellular Telecommunications and Internet Association) convention-which showcased several acres of upcoming cellphone and wireless technology-the focus was less on material goods than on what you can do with them. The exhibits boasted no gotta-get-it-now phone, but they did promise many ways to do more with the phone you already have. From file-sharing to postcard-making, the latest possibilities go far beyond mere talk.
