Pros: meets all my performance needs have been running 4x of these (2 sets of RAID 1) for data backup / NAS for over a year, in a remote area that is hot/cold/dusty and loses power frequently (hey, at least its dry!), zero reliability problems so far. I was sure I'd have one dead by now, but they keep on spinning with zero performance degradation.

Cons: priced slightly higher than I'd like to pay, but have had perfect reliability for four of these for over a year

Pros: excellent value good performance love the exhaust fans out the back, never have to worry about it overheating when I'm using it on my lap/in bed/on my belly (cat loves it too) the auto-switching between dedicated graphics / on-board graphics lets the battery just keep going and going, very nice

Cons: hard drive seems to be the slow link in the chain, regret not getting an SSD when you connect an external display to HDMI, you cant "duplicate" the image (windows 8.1), the image can appear on 1, or on 2, or be extended to both 1 and 2, but it cant show the same image on both 1 and 2 (think this is a side-effect of the dual graphics card setup)

Overall Review: i wont call it a con, but: after two years of lugging around, the power connector on the motherboard has a poor connection. I have to do odd power cord gymnastics to get it to take a charge, and it will sometimes stop charging. not a con, but: the 14" screen is a touch small, and lower resolution than I'd like, but I knew that going in (its a part of how they make it such a great value)

Pros: low cost straight-forward configuration very reliable easy to remotely manage (the auto-monitoring and notification system is a godsend)

Cons: processor is slightly under-powered for what i'm asking it to do. I notice it, but none of my users do. I have one of these installed in a remote area that frequently loses power (I know I should put an UPS on it, but, meh), and it doesnt always recover by itself. I have to manually turn it back on 1 out of 5 power losses.

Overall Review: I have one of these servicing data backup and network storage for small business network (4 computers). It also performs video streaming at night, everyone's very satisfied.

Pros: low cost long battery life (i use these mostly at work, they last all work day) excellent range: powers through walls and meat bags better than most BT equipment I've tested. can line of sight > 100 ft (impressive!) high volume with surprisingly good bass. They're actually a bit too loud for my tastes (at least when paired with my old Motorolla Droid phone)

Cons: shipped without the tips for the ear buds, but they're refurbished, so maybe not getting someone else's ear wax tipped tips is for the best I modified some disposable ear plugs (the little orange foam ones) to serve as tips, might have been for the best, as they also passively improve the noise cancellation i dont notice a difference when the noise cancellation is on vs. off, not sure it does anything I have a thick neck (19" collar), and the headphones are just barely too small for me (they get slightly uncomfortable if i dont readjust them every 20 minutes of so).
