The R7 looks and feels like an upscale, 15-inch, ultrabook-style laptop. The aluminum body is thin and feels sturdy enough for regular on-the-go use, and at 5.3 pounds, it's on the heavy side for a thin midsize laptop, and would be a bit of a back-breaker for daily commutes.The Acer Aspire R7-572-6423 desktop-replacement laptop measures 1.1 by 14.8 by 10 inches ( HWD) , and weighs 5.22 pounds. The R7-572-6423 winds up being far bulkier than the Sony VAIO Flip 15 ( SVF15N190X) , which offers a similar sort of flipping and folding 15-inch display, but weighs under five pounds.
