With phones now reaching paper levels of thinness it was only a matter of time before laptops went the same way. So Tosh has run its already slight R200 series lappy through the mangle to create the 12.1in widescreen R500.Measuring just 19.6mm in the vertical, it's the world's thinnest laptop with an optical drive, thanks largely to the fact that its the only portable to use impossibly thin 7mm DVD burners. It'll squeeze in a reasonable 1.2GHz Core 2 Duo U7600, a Vista Business-friendly 1 gig of RAM and a meaty 120GB hard drive.Want a few more firsts? Well, it's also the world’s first 12.1in widescreen notebook with a backlit LED screen and it's got the longest battery life of any 12.1in widescreen model, promising 'up to a full work day' – so that'll be about 12 hours in our case then. Honest.But wait, there's more, Tosh is also eyeing up the crown for the world's lightest 12.1in with a 64GB solid state disk model, weighing just 780g and due out later in the year. What a lightweight.Don't expect all this thinness to go unchallenged, though. Panasonic is rolling out its 7mm DVD burner to all PC makers. Suddenly our MacBook Pro's looking decidedly porky.Essentials Toshiba Portege R500-series Price: £TBA (from $2000 in US) On sale: TBA Contact: Toshiba Related stories: Honey, VIA shrunk the laptop Gadget of the Day – Toshiba LapJacks Tosh touts new sliding smartphones
