The IdeaPad Z580 doesn't look like a typical budget notebook with its sleek brushed aluminum palm rest and lid. The design is quite detailed too; I like the fancy speaker grille above the keyboard and the touchpad's beveled edge.
Like most Lenovo notebooks, the build quality is again surprisingly good for a budget laptop. The chassis is stiff and no ripples show up on the screen when you press in on lid from behind. Ideally a notebook's internal parts should be subjected to as little flex as possible so they can last a long time; flex is bad for circuit boards. Thankfully, the Z580 feels very solid for a consumer laptop in this price range ($500-$750). Attention to detail is another positive aspect of this notebook; there are no rough or unfinished edges.
Users looking to upgrade the Z580 will find easy access to the storage drive, RAM and wireless card through a single access panel on the bottom of the notebook. The battery is also user-replaceable.
The Z580 has a respectable array of input/output ports including two USB 3.0 SuperSpeed ports, two USB 2.0 ports, HDMI and a media card reader. It lacks an ExpressCard slot, eSATA and DisplayPort. Still, you would be hard pressed to find a budget-priced, 15-inch consumer laptop with ExpressCard slot and DisplayPort so we can't complain too much.
Lenovo's 'Chiclet' style keyboards are amongst the best out there in terms of feel. The Z580's keys have plenty of travel and are able to provide ample tactile feedback. The keys make pleasant clicking sounds which add to the feedback. The keyboard feels solid with zero flex. The layout is good; all the keys are in their expected positions; the only nuance is that the keys on the number pad are about 2/3 the size, which takes some getting used to. Keyboard backlighting is not available on the Z580.
The oversized touchpad is actually a clickpad with a press-able surface. While I still prefer a traditional touchpad with separate buttons, this clickpad is actually quite good; it doesn't take too much effort to push down and it has an excellent smooth surface. The clicks are a bit louder than I prefer but that's my only real complaint.
The Lenovo IdeaPad Z580 represents a great value thanks to its combination of good build quality, a solid keyboard and touchpad, good performance, and six hour battery life. The only areas that need improvement are the screen -- 1366x768 is low and hard to be productive with -- and speakers, which sound tinnier than expected. The fan also has a slight whine but isn't loud enough to be annoying.
