Not only that the rumoured Motorola X-Phone would be one of the most powerful smartphone on its purported Q3 2013 release date, buyers will be treated too to a rainbow of choice come the Key Lime Pie handset's debut.

A new report from PhoneArena has suggested that Android buyers will find it hard to pick from the attractive colour options that the X-Phone will offer once the device becomes available, which expert believe will likely happen on August 2013.

That will be a few months after the annual Google I/O Developers Conference where the tech giant is expected to introduce the new product together with the latest Android version - Key Lime Pie.

It is unclear, however, if the plan is to accessorise the X-Phone shortly after its commercial availability or Google and Motorola would package the wide array of case colours as out of the box offerings.

If true, the Google and Motorola flagship would be the first smartphone to retail that presents consumers with so many choices to suit their preferences. The move would be a hit especially for buyers who really invest on jazzing up the gizmos they use.

In effect too, the X-Phone would be some steps ahead of competitors in terms of handset customisation. The iPhone, for instance, only comes in black and white while Samsung sells its flagship phones in as many as six colour variants.

Reports, however, are rife that Apple is seriously considering wrapping the iPhone 5S and its low-cost edition in bright colours.

Google remains mum on Motorola X-Phone details but experts believe the upcoming handset will receive generous hardware specs with focus on compact form-factor and insanely great camera features such as GPS capability.

The smartphone is also pinpointed as the first carrier of Android 5.0 or Key Lime Pie, edging out the Nexus 5, another of Google's rumoured device set for unleashing later this year.

Analysts are convinced too that the Motorola X-Phone will largely sustain Google's hardware retail approach. The business model relies on selling powerful but affordable gadgets in hopes of luring more traffic for Google's web-based services.
