I have been a VoIP (SIP) fan-girl for over a year now and as such I have searched for or tested lots of related devices, clients and clever services. This is a list with the best SIP clients on a wireless multi-function mobile device, read on for more.

With holiday PC sales apparently unscathed by the lack of Windows Vista, Microsoft reported quarterly earnings Thursday that topped expectations and its own forecast. The software giant said it earned USD 2.63 billion, or 26 cents per share, on revenue of USD 12.54 billion, for the three months ended December 31. That compares with earnings of USD 3.65 billion, or 34 cents per share, on revenue of USD 11.83 billion for the same quarter a year ago.

Access, the company behind the former PalmSource, announced Thursday it is renaming the Palm OS operating system to 'Garnet OS', rolling out a new 'Access Powered' logo that replaces the 'Palm Powered' branding used on a wide range of handheld devices. In September 1995, Access purchased Palm OS and its owner PalmSource, which was spun out of Palm, Inc. following that company's separation from former parent 3Com. PalmSource changed its name to Access Systems America in October, selling the rights to the 'Palm' brand name back to Palm, Inc.

"The KDE Project today announced the immediate availability of KDE 3.5.6, a maintenance release for the latest generation of the most advanced, powerful free desktop for GNU/Linux and other UNIXes. This release includes a number of fixes for KHTML, Kate, kicker, ksysguard, and lots of other applications."

"Does performance suck on Vista when compared to XP? That's what I was set out to find out. I was worried at first, since the performance in Beta 2 was quite bad. While there is indeed a performance decrease, it's quite minimal as you'll find out."

As revealed yesterday, Mandriva today released a special version of its Mandriva One 2007 distribution, using the 'Metisse' 3D environment (which is actually not a 3D environment). "Metisse is a window manager developed by the In Situ project. Available under the General Public Licence exclusively for Linux, Metisse differs from a classic 3D desktop ('the cube') in the way that it offers innovative windows interactions, thus enforcing work efficiency."

"The openSUSE team announced today the open sourcing of our openSUSE Build Service. We believe that it is not only important to release an excellent Open Source distribution but also create it in an open way with Open Source tools together with the openSUSE community. Releasing the build service as Open Source makes the complete project build on Open Source."

Genesi has 'announced' it is going to release AmigaOS4 for their EFIKA motherboard as soon as the next release of MorphOS is released. "We have clearly indicated in this thread, we don't need Hyperion's support to port OS4 to the EFIKA - legally or technically." True to the Amiga scene of the last few years, a discussion spanning 300 posts ensued. My take: I actually advocated 'porting' AmigaOS4 to Genesi hardware last year, but I do hope it all happens within the boundaries of the law and that the developers get what they deserve. Update: The latest post asks an interesting question.

"Linspire CEO Kevin Carmony says his company is opening up its CNR software download and management service to other Linux distributions because "Linux really needs an easier way to find and install software, regardless of which flavor of Linux you're using." According to Carmony, Linspire has been working on this project more more than a year. To find out more about how this bold new program is going to work - and how it benefits everyone involved - Desktoplinux.com conducted the following short Q&A with Carmony via email."

GNOME 2.17.90 has been released; it's the sixth development release en route to GNOME 2.18, which is planned for March 2007. "This release marks the start of the UI Freeze. If you break the freeze your picture will be added to the HIG under the heading 'Banned for Life' and will have to live with the stigma of causing the 'worst freeze ever'."

"For some time now, I've been working with members of In Situ team to integrate their Metisse software in Mandriva Linux and it is really exciting. Mandriva will announce very soon (today or tomorrow) Metisse will be part of Mandriva Spring 2007 and is also available as a Live CD based on Mandriva 2007.0 and GNOME right now so everybody can try Metisse right now and report bugs."

CNet has reviewed Windows Vista, and the concluded: "Perhaps we're spoiled, but after more than five years of development, there's a definite 'Is that all?' feeling about Windows Vista. Like cramming an info-dump into a book report the night before it's due, there certainly are a lot of individual features within the operating system, but the real value lies in their execution - how the user experiences (or doesn't experience) these - and like the info-dump, we came away shaking our heads, disappointed." Additionally, Vista's OEM pricing details are out and about.

Microsoft announced that it was extending technical support for home Windows XP operating systems, a signal that it was not abandoning them for Vista software launching next week. The Redmond, Washington software giant said the 'support life cycle' for Windows XP Home Edition and Windows XP Media centre Edition would be stretched to April 2009. Similar support would be provided for users of Windows XP Professional, according to Microsoft.

"Once upon a time, when DOS walked the earth, the command line was the primary user interface for most of our computers. Then, Windows came along, and Microsoft seemed set on leaving the command prompt to dry up and wither into obscurity. Fortunately, Microsoft has again turned its attention to the command line and, in so doing, has produced one of the most compelling new Windows features eWEEK Labs has ever had the pleasure to test: Windows PowerShell."
