Kensington has been touting its DisplayLink Dual Monitor Adapter
since before it even had a product to show off, but the company's now apparently finally gotten its act together and pushed the device out the door. Like similar devices, this one will let you add a second monitor with nothing more than a USB connection, or up to six monitors if you want to string a bunch of the adapters together. You still won't get more than a 1440 x 900 or 1280x 1024 resolution, however, but thanks to those recently released drivers
, you will now be able to use it with Macs in addition to XP or Vista-based PCs. Unfortunately, as is often the case, the price has taken a bit of a jump since the company's initial estimates, with it now running $120 instead of the even $100 we were first promised.
