IOGEAR's new optical Memory Mini Mouse 800dpi (Memory Mouse) is an excellent alternative to touchpads, cumbersome mice and external hard drives. This unique input device allows users to carry documents of up to 128MB around in a tiny, ergonomically designed and lightweight mouse. In many cases, the Memory Mini Mouse eliminates the need to bring a laptop on a business trip since it can be used on any Windows-based computer at the client's location. The Memory Mini Mouse also features a retractable cable that is quick and easy to manage, without the tangles and mess of standard cables. In addition, the Memory Mini Mouse's 800 dpi resolution offers twice the accuracy of standard mice, offering greater precision and accuracy for graphics or other detailed projects. IOGEAR's Memory Mouse consumes virtually no room in laptop carry-bags, works on any surface, and needs just inches for accurate cursor movement. The elegant, contoured design offers comfortable use for hours, and its greater speed reduces excessive and potentially harmful arm movement. This unit is USB ready, Plug-n-Play and hot pluggable.
