Dell's V305w prints, scans, and copies, and it does it all without wires. That's right, it's a Wi-Fi-enabled all-in-one. And it's on sale for a measly 60 bucks, shipping included! (Make sure to choose "3-5 Day Delivery" when you get to the checkout.)
This is a brand new model from Dell; it launched just a week ago, so it's surprising to see such a steep discount already (it normally sells for $129).
The V305w features a 100-sheet input tray, borderless photo printing up to 8.5x14, and media-card slots for printing photos without your PC. (No preview LCD, alas.) Dell promises 25 pages per minute for black printing, 18 ppm for color, and 17 ppm for copying.
You'll pay around $19 for replacement blank cartridges and $25 for color. Wish I could point you to some professional or user reviews, but there aren't any yet. Taken at face value, this looks like a pretty sweet deal on a wireless all-in-one.
