It's a svelte 2.65 pounds – lighter than both the Lenovo Yoga 900 (2.84 pounds) and the Asus ZenBook UX303 (3.2 pounds). No matter the surface – table, tray, or lap – the Z30 never tips or wobbles it sits flat even when you have the screen leaning all the way back. The device has a thin, clean profile and is very well-balanced. The Portégé Z30 at least ticks all the compulsory Ultrabook boxes. Like its exterior, the Z30's interior reinforces the 'no flash here, just business' theme. The Cosmo Silver paint job is also too dark to effectively contrast against the black keys. It's not unattractive, nor is it striking or particularly original. Its keys and bezel are black, which gives the interior a two-tone appearance. Even post-modernists will admit silver and wood are rarely complementary. But this aesthetic fits better on Toshiba's black devices than its silver ones.
The Portégé Z30 's 'Cosmo Silver' exterior features the typical Toshiba flair: a subtle etching made to mimic wood grain.
