I have a Acer Aspire One, 11.5 inch, with a 160GB harddrive, & 2GB of Ram..I added the 2'nd GB of ram. ,( for 4 or 5 yrs.or more)..One of the first one's out. It has not given a bit of trouble , & has been a great net book. I would think that the Acer One with the larger HD would be a great netbook.. One thing that may be making my old Acer run great, is i'm still on windows XP.. I also have a new HP DM4, with a 640gb HD, with 8 gb ram, with windows 7 & it is fast.. 7 seems ok on it, I had two Dell 15 " laptops, one with XP & one with Vista, Vista was junk, & i gave the laptop to a relative, & had Windows 7 installed, which helped , but still gives some problems.. probably beause of smaller HD The Acer One HAS BEEN GREAT , just a little slow with the back arrow sometimes..Quality wise, In my opinion, it's a tough little netbook, & i'm a retired mechanical engineer, & I always try to purchase quality products. P.S., I also do not represent Acer , or have anything to do with the company, So this is my own, unbiased opinion.... Regards SP.
