Summary: This laptop can't handle very much. Try to run more than one thing at a time and it slows to a crawl. I know it's not the most powerful laptop and it's priced pretty low, but for 6GB of RAM I would expect it to perform better. I've had other laptops with similar specs that didn't have the same issues.
Summary: I got my Lenovo Z580 in early 2011 and it works amazingly, I really do love it. The processor is just about perfect, as with the RAM, amount of ports, the screen, etc.... My only problem with this computer is the fact that after about 8 months of usage the connection to my wireless network stopped functioning properly. All I can do with the internet is instant message and access google hosted sites, and very slowly at that.
Summary: I've been using a Lenovo Thinkpad Edge for the last two years for work and love it. So I bought my wife the Ideapad z580 the other day. For the money you can't get better specs. Intel core i5 processor, 8gb Ram, 750gb hardrive were included in a $499 deal at Staples. The other laptops of similar spec were at least $100 more and then some. The feel and handle of the z580 are great.
Summary: Laptop is fine in many ways but you have to buy a seperate mouse as the track pad is insanely terrible. I have owned or used 15 or so laptops in my lifetime, and this is by far the worst. To make it work even remotely ok, you have to turn of a ton of the advanced features. Based on that, I wish I didn't buy this laptop. Lenovo has a bad return policy so I am stuck with it.
Summary: When I first bought this laptop I loved it so much, the colours the decent amount of spec and its nice reasonable price tag. But wow this thing looked nice all in red etc. Unfortunately WINDOWS 8 wanted to update upon doing so my laptop well put it this way it told me how much it didn't like WINDOWS 8 update that it was doing, so it strangely enough rendered its self useless and I could no longer use my lovely new Laptop.
Summary: Well constructed, smart looking and powerful for the price, but...... I am normally a placid sort of person but Windows 8 is turning me into a dangerous psycho prone to throwing objects and shouting profanities. Upgraded to Windows 8.1 but still finding it the most annoying operating system ever. Desktop is full of junk from Lenovo and other vendors of rubbish that all take time to get rid of.
