I bought the 500GB HDD machine for my wife.  She works for a large international company and each employee is given a new Lenovo ThinkPad when they start their employment.  She felt comfortable using her ThinkPad for work and therefore I thought buying her another one for home would be fitting (she's been debating between a laptop and a two-in-one device for a while now).  I think the best compliment that I can give for this purchase is that the machine is so well refurbished that you'd NEVER, EVER know it wasn't brand new.  Now, I did tell her that it was refurbished so she could tell me how it compared to her work device.  She's been very honest in saying that she likes her gift quite a bit and she's 100% sure that it's faster than her current work device which is almost 2 years old.  This machine didn't come with Windows (Excel, Word, Visio, PowerPoint, etc.)  so we'll solve for that at some point but otherwise she's very pleased that it does have Microsoft OneNote and OneDrive.I felt secure purchasing this for my wife and her pleasure in using the device each day has validated that it was a good buy.  I wouldn't hesitate to buy another refurbished device from this seller.  Give it a shot if you're debating!
