The dev folk over at Tapbots have just unleashed a major overhaul to their famed Twitter client. Tweetbot 2.0 not only sees the addition of a few new traits and a design refresh, but it's also on the receiving end of some welcomed iPad compatibility (iOS 5 only). Though, it's worth mentioning the app isn't universal -- so you'll have to cough up three bucks for the slate variant, even if you've already got the iPhone edition. Amongst the new goodies is a renovated timeline view with pic thumbnails, an optional New Tweets bar, auto-refresh, and a one-tap system for links. If you're still rockin' the official birdie app, but are looking for something a bit different, then hit up the source link below to scan through the rest of the features and see if it's enough to make you fly the coop.

New details have emerged about the ongoing Apple-Motorola drama in Germany, courtesy of a court document uncovered by FOSS Patents. The two companies have been engaged in a patent battle of swelling proportion these past few months, with the most recent wrinkle unfolding on Friday, when Apple promptly removed (and returned) its 3G / UMTS-enabled iPads and iPhone 4s from its online German store, in response to a court ruling. At issue in this particular case is a Motorola patent that Apple wants to use under FRAND obligations, but Moto apparently isn't willing to license its technology for free. According to a court filing, the handset maker is asking for 2.25 percent of Apple sales in return for the license, though it remains unclear whether this pertains to sales of all products or, more likely, the 3G-enabled devices under consideration in court. Either way, though, Motorola would stand to see quite a bit of extra revenue, especially considering that Apple's iPhone sales have totaled about $93 billion since 2007. Under Motorola's request, the company would have made about $2.1 billion from these sales alone -- not to mention the payments it'd see from iPad sales, as well. Apple, meanwhile, has filed motions to access Motorola's licensing agreements with Nokia, HTC and other manufacturers, in the hopes of exposing a double standard.

2011: the year Smartphones supplanted computers, at least according to the bundle of spreadsheets that just arrived from Canalys Research. Vendors shipped (shipped, not sold) 488 million of the devices, compared to 414.6 million "PCs," which erroneously includes Tablet PCs of all shapes and sizes. Looking at Smartphones exclusively (IDC's numbers from yesterday concerned all mobile handsets), Apple remains king of the hill having shipped 93.1million iPhones. Samsung is close behind, with 91.9 million and Nokia is kicking along in third with 19.6 77.3 million. For all of the doomsaying around RIM, it's nestled in fourth, although Canalys chose not to include its numbers. Framing the research as "PCs versus Smartphones" isn't the wisest, given the fragmentation and hybridization prevalent in the market today. Drilling down into those numbers, we learn that 63.2 million tablets were pushed out last year, cannibalizing netbook shipments (dropping 34.5 percent in a year), but desktop and laptop movements remained relatively stable. We've included the full report and the most relevant table of data for your perusal and insight (hint: there's no points for saying netbooks are on the way out).

Correction: Nokia sold 19.6 million phones in the last quarter, but sold 77.3 million in total last year.
