Summary: Work provided E5520 I7 with 128 ssd. The unit is nice. I wouldnt say great but after using it for a couple of days it is a solid unit. I like the wrist rest. I couldnt purchase the 256 ssd in Australia even though it is advertised on the website. However, I have now grow to hate DELL. It is imposible to get support fromthem. It takes weeks for them to adress a query and the support is useless. It is easier to do a web search.
Pros: The really good thing with my unit is the 9.5 hours of battery using the Win 7 balanced setting.
Cons: No support from dell, no parts available from dell, In short Dell lack of support and terrible website.
