We'd have gone with "smaller than a breadbox," but book-sized seems to work just as well, when describing Giada's new mini-PC. The i53 packs an Ivy Bridge Core i5 processor standard (i3 and and i7 versions are also available), 4GB of RAM and a 500GB hard drive into its sub-one kilogram, bookshelf-ready form factor. The system supports USB 3.0 and HD video and comes with a colorful remote control, so you can boot it up from a distance. The i53 should sell for around $520. More info can be found in the press materials after the break.
