And Tuesday, Google boosted expectations with an invitation-only press event scheduled for next week at the company's Mountain View, Calif. headquarters. According to the invitation, the event (scheduled a thunder-stealing two days before the start of CES) is an "Android press gathering."
Google has maintained an Apple-like silence on matters related to the phone, but industry watchers expect it to run on Google's Android operating system and feature a high-resolution touchscreen, 5 mega-pixel camera, Wi-Fi connectivity, compass and more.
One of the phone's most interesting features, however, is that it will be sold directly from Google without the typical long-term telecom carrier contract.
But even aside from the Nexus One, tech bloggers and analysts say 2010 will be a banner year for Google and its Android operating system.
"[Google] has two flagship products -- the Droid and now this," said the blogger behind the popular tech blog Boy Genius Report, who asked to be referred to as "BG." "I really see Android as being big this year, if anything as an alternative to the iPhone."
Just a year ago, T-Mobile's G1 "Google phone" was the only phone on the market to run on the Android operating system. But in the past year, a handful of other smart phones have come on the scene, including the recent Droid from Verizon and Motorola.
And analysts expect more than 50 new phones with Google's Android operating system to ship next year. Netbooks and other devices are also expected to increasingly run on Android.
But BG said he expects significant activity in the mobile market in general.
Between about 15 phones expected to come from Research in Motion (which makes the BlackBerry), the steady stream of Android phones and a new and improved Windows mobile operating system, he said the field was shaping up to be an interesting one in 2010.
"Next year, there will be a huge push for 3D," said Enderle, adding that it's the biggest technological innovation in television since color.
But, he added, given the cost of the technology, consumer reluctance to replace current TVs and, of course, the glasses, the adoption won't be fast.
"We might call this the 3D decade instead of the 3D year," he said. "But the content is increasingly going to be there."
