Pocket-lint - Sick of those £50 iPod docks that spew out meek music? Then try Arcam’s rCube for size; Wi-Fi meets Hi-Fi on this ‘pod-friendly speaker that’s about as high-end as it gets at this size. Ready for more good news? It’s portable. Yup - unplug the 5kg rCube from the mains and its internal Lithium-ion battery will keep going for between 4 and 8 hours. There’s even a grip-hole hidden just behind the iPod dock for carrying the thing around.
