I got the refurbished 14.1 i7 HP at the end of 2012. It's a great computer, especially after expanding the RAM to 16gigs. Very solid: aluminum case and stiff keyboard base. Good resolution (1600x900) and decent dedicated graphics. Another plus is that you can take off the bottom access panel without a screwdriver, something I've never had in the past with Lenovo and Dell. AND it's still Windows 7, for anyone concerned about the newer systems.
It's a little heavy, but switching to a SSD will shed some weight. It's a good size, so unless you're tiny or ridiculously weak, the weight shouldn't ever be an issue.
However, remember that these are refurbs and may or may not still have problems when they send them out. Mine came with a dead pixel right in the middle of the display, which causes a faint line that runs across the screen.
It's obnoxious and ridiculous that they'd resell a product with such an obvious (and easy to fix) defect, but it's a gamble. Ridiculous price for a great system.
