Acer unveils AMD-infused Aspire Z3100 AIO, Revo 3700 nettop now available for $349

. Acer's taken the cue with two new desktop SKUs -- one each in the nettop and all-in-one categories. First with the latter: the 21.5-inch AZ3100 all-in-one (pictured). A tier lower than the AZ5700, this one lacks the multitouch and TV tuner, and instead utilizes a 2GHz AMD Athlon II 170u processor, NVIDIA GeForce 9200 graphics, 3GB RAM, and 500GB HDD. Add in a DVD drive, webcam, HDMI, six USB 2.0 ports, Windows 7 Home Premium, and a side chassis for "cable management." It does best its older brother in the price category, though, at just $599 -- about five Benjamins lower.

As for the Aspire Revo 3700, it was actually announced earlier this month, but now we've got the skinny on this book-sized nettop's price and availability. That'd be $349 for the tag, and a street date of approximately... now, according to the press release.
