The EMP-1715 is a small projector that can connect via USB and even do multi-screen displays—up to four screen simultaneously, all with different content. The USB transferability also means that you can simply plug a USB flash drive into the projector and present slideshows without the need for a computer. The connectivity options don't end there; this projector also supports 802.11a/b/g wireless transmission. Oh and did I mention it only weighs a little over three pounds? At 2700 lumens brightness, this projector is ideal for a more business application, but it can still stream movies over the Wi-Fi connection, so don't eliminate it from your home theatre, yet.
