Ubuntu Phone looks set to shake up the way we interact with our smartphones and the apps we've installed on them. Rather than laying out all the apps separately in grids as with Android and iOS, Ubuntu Phone is bringing in the revolutionary idea of "Scopes", which as Cristian Parrino, VP of Mobile at Canonical claims, is "a game changer".
Ubuntu Phone is looking to integrate content and services via "Scopes", which will integrate various apps and services into an easy to use interface, so users don't have to scroll through screens of icons.
For example the NearBy scope will aggregate local services centred around where you are and what you're doing, giving you reviews of local restaurants nearby, as well as the weather in your area. It should mean you no longer have to open up separate apps or web pages to view all of this information.
It will go on sale exclusively across Europe for €169.90 (around £127, $194, AU$249) on Monday 9 February in a flash sale. The website for the sale and the exact time the virtual doors will open will be revealed on @Ubuntu and @bqreaders on Twitter.
If you want to get your hands on one, you'll need to be quick as there will only be a limited amount of BQ Aquaris E4.5 Ubuntu Edition devices available on Monday. Rodrigo del Prado, Deputy Director General of BQ, told us that further flash sales, and then more widespread availability across Europe will follow in the next two to three weeks.
A number of networks in Europe such as amena.com, giffgaff, and Portugal Telecom will offer SIM bundles with the BQ Aquaris E4.5 Ubuntu Edition.
We spoke to Cristian Parrino, VP of Mobile at Canonical, the company behind Ubuntu Phone, who told use that "Launching a new product is a journey, this is the first step", and that for the time being Canonical is focusing on early adopters who are bored of iOS and Android, rather than fighting for shelf space among more well known brands.
Time will tell if this direction will pay off and Ubuntu Phone can get the attention of disgruntled iOS and Android users.
