The Ubuntu MATE 15.04 version for Raspberry Pi 2 has been quite successful, and it seems to soon become the favorite OS for the small mini-PC after the official Raspbian OS.
The image is based on the regular Ubuntu armhf base and is optimized for the Raspberry Pi 2, one can comfortably use applications such as LibreOffice. Since, microSDHC I/O throughput is a bottleneck it is recommended to use a Class 10 microSDHC card for best performance.User needs a microSD card which is 4GB or greater to fit the image. The file system can be resized to occupy the unallocated space of the microSD card, similar to Raspbian.

The good news is the latest version of Ubuntu MATE v 15.10 is also coming to Raspberry Pi 2 and will be available for download on October 22, 2015.

With a phenomenal increase in mobile and tablet users, converged computing is definitely going to be the next big thing in the world of technology. To elaborate, "Phone–PC convergence" means a single app Eco-system and user-interface across mobile, tablet or Desktop computing devices. The technology industry has already prepped the end users for the shift. Ubuntu was without the doubt one of the first major OS name to afloat the idea and even start working on it, with options ranging from Ubuntu Edge, Ubuntu For Cars or the Nexphone concept the idea is now well conceptualized and waiting to became a reality sooner or later, recently Microsoft also joined the race with Windows 10 and started talking about the idea of "Universal Apps" across the Windows devices Eco-system. Microsoft has also taken the first step to make way into the Linux stronghold of "Internet of Things (IoT)" devices with it's "Windows For Devices" initiative and has already started offering free Windows 10 for Raspberry Pi 2.

In a recent presentation Mark Shuttleworth founder of Canonical’s Box (the company to market commercial support for Ubuntu) focused more on the convergence, specifying that currently Ubuntu’s phone application platform can already resize and fit applications to fit the different screen sizes, including smart phones to windows desktop screen sizes.

Here is a peep on how both Windows and Ubuntu are being remodeled around convergence and what are their USP's.

The beauty of Android is that it allows users the flexibility to tweak things to the extent that their devices can run other operating-systems. Ubuntu Dual Boot Installer takes advantage of this and has now released an app allowing users to run Ubuntu and Android on a single device as a dual-boot system. A user can install and use fully functional Android and Ubuntu images and switch between them easily, on each-side, an app with a simple user interface enables them to boot back and forth at the tap of a button.

We recently shared a story showing the versatility and power of open-source computing with Linux, further strengthening the claim, Linux has now got another feather in it's cap when Ubuntu became the OS which is now not only powering Desktop, Laptops, Netbooks and mobile devices but also Self-driving Google Cars as unveiled by the following Google presentation at the embedded Linux conference.

As detailed by Google, they are using a customized version of the Ubuntu Linux OS optimized for real-time usage in their driver-less cars, the video also shows how Google modified the Ubuntu operating system for these particular usage needs and achieve exactly what they needed.

Moving ahead with it's goal to converge the desktop and mobile computing environment, Canonical the developers behind the popular open-source, Linux distribution "Ubuntu" have now launched the crowd-funding for the first-phone to feature their Ubuntu Mobile OS announced earlier.

Named "Ubuntu Edge" the gadget is backed by some powerful hardware specifications like fastest available multi-core processor, at least 4GB of RAM, and massive 128GB of storage the phone will also feature elegantly finished textured amorphous metal casing made from a single sheet, a 4.5 inch screen with amazing dynamic range and color accuracy for maximum clarity protected by nothing else but a pure sapphire crystal glass which is so hard that only diamond could scratch it. On the software front the phone will feature dual-boot between Ubuntu Phone OS and Android, and will convert into a fully integrated Ubuntu desktop PC when attached to an external screen. Don't miss the "Ubuntu Edge" teaser and introduction videos posted below.

Apple Mac OS X provides a clean and easy to use interface and is desired by non-Apple hardware users, we have seen Mac OS X themes and total customization packs for Windows allowing users to get the look on their PC's running Microsoft Windows OS. Ubuntu on the other hand, also features a nice user-interface and there exist many Ubuntu customization packs for Windows.

Instead of hacking your way trying to install Apple Mac OS X on PC hardware, how about a totally free, Ubuntu Linux based complete operating system with sleek and user friendly Apple Mac OS X styled user-interface, minus the much debated Ubuntu sponsored search links (Adware) without the unity shell. Welcome to Pear OS 7, an easy to use Ubuntu based Linux distribution which comes pre-configured with free apps and drivers to allow use of your exisitng PC files, printers, cameras and MP3 players. With option to install and use thousands of free applications.

If Apple iOS, Google Android, Microsoft Windows Phone, Blackberry OS, Symbian, Mozilla Mobile OS, Nokia MeeGo and Sailfish does not satisfy your need for the perfect, most hackable and customizable mobile operating system, here is an exciting "open-source" candidate with some promising features from the leading Linux distribution - Ubuntu.

Ubuntu's developer Canonical has announced their entry into the smartphone business with first public glimpses and features of upcoming Ubuntu for Phones. The Linux-based operating system will offer users an seamless experience on Desktop, PC and Mobile with some exciting features and an "android compatible kernel" so existing Google Android users can simply install and use Ubuntu on their phones. While Ubuntu for Phones will be available in 2013 for users to install on existing hardware, handsets powered by the OS will hit shelves in 2014. Canonical released an extensive video preview and this looks really promising - have a look yourself below.

If we look at hardware specifications of today's smartphones they are more then capable to run an powerful desktop or laptop computer, so wouldn't it be a "smart idea" to use a single smartphone hardware all across your devices like tablet, laptop and desktop ?

The idea of a single brain multi-utility computing device like RollTop is not new, but new startup NexPhone is not only modern, practical and innovative but it takes this to an all new level. By using a single brain (hardware to store and process your data) it not only makes things more affordable but also more manageable. Users will no longer be needed to buy different internet subscription plans and services for multiple devices, but also will have all there files, music , videos and software's at a single location without needing the cloud to synchronize in between.

The idea is to have a NexPhone which would be an Android smartphone coupled with Ubuntu, which docks with connectors like tablet, notebook, laptop or desktop computer to provide the device functionality of your choice. The startup needs crowd-funding to get into production which seems sufficiently feasible, a nice introductory video and other related information after the jump.

Want to enjoy the popular desktop Linux OS Ubuntu on your Android powered mobile device, it can't get easier than this - the free "Ubuntu Installer" app from Android Market. The application allows users to install and run "Ubuntu" inside Android - The market application installs an customized Ubuntu 10.10 image optimized for the ARM processor allowing users to run a full Ubuntu system within android. The great thing is users can make calls, text, and use other android features without having to reboot their phones.

Success of Apple iPad has sparked a new era of multi-touch enabled portable computing devices, with iOS, Windows 7 and Google Android already fighting for share in the niche Ubuntu is all set to enter the space with uTouch - a multi-touch friendly stack for Ubuntu Unity Shell enabling usage of touchscreen devices with the popular free Linux operating-system.
