TigerDirect offers the Logitech N700 Speaker Lapdesk, model no. 939-000287, for $49.99. Pad your order over $50 to bag free shipping; otherwise, shipping adds $6.59. (These eraser refills cost 99 cents.) That's the lowest total price we could find by $16, although we saw it for $7 less last spring. This USB-powered padded base features integrated stereo speakers, an angled riser, built-in cooling fan, and more.
