The problem with claiming some kind of landmark status of being the lightest or thinnest or fastest at something is that sooner or later – and more likely sooner – someone will whip the title away from you.
Take the Sony Ericsson Xperia Arc and the Samsung Galaxy S II. Both of them were claiming to be the world's slimmest smartphone at Mobile World Congress last week. Fast forward a week and the argument no longer matters, as both of them are now wrong. Instead, the title is heading the way of the wafer-thin NEC Medias over in Japan.
The Xperia Arc tapers to just 8.7mm thick at its thinnest point, which was good enough in January but falls short of the Galaxy S II's even thinner 8.5mm profile.
But now Akihabara News tells us of the Medias with its wafer-thin 7.7mm cross section, making it comfortably the thinnest phone on the market before either of its better known slender rivals even head into production.
Not that it matters a whole lot to us here in the UK. The Medias is set to be announced on Thursday as part of Japanese network Docomo's spring refresh, and there's nothing so far suggesting it will ever make it beyond Japan's shores.
Aside from its slimline profile, the NEC Medias seems to be aiming towards the budget end of the smartphone scale. An 800MHz processor sits underneath a large 4in screen, with a 5.1-megapixel camera on board too.
Android is the operating system of choice, but it's Android 2.2 Froyo rather than the newer 2.3 Gingerbread.
