webOS-shedding PC company HP has now expanded its peripheral offer through the release of two new wireless mice, the X4000 and X5000. Both models measure 4.21" (L) x 2.64" (W) x 1.52" (H) and feature an ambidextrous design, a 1600 dpi laser sensor, 2.4 GHz wireless connectivity, an operating range of up to 30 feet, and a micro receiver which can connect up to five devices (to save precious USB ports).

The X4000 has a battery life of up to 30 months and a 'regular' scroll wheel, while the X5000 comes with a touch scroll and lasts up to 24 months on a pair of AA batteries. The X4000 sells for $29.99 whereas the X5000 is available for $39.99.
