I like dell, I work in IT and we have about 400 users.
Their pro support is very good. I don't know about home support.
Anyways, take a look at the Dell Outlet webpage.
They have some nice deals, and some nice coupons on there also.
If you buy a business line laptop or desktop, you usually get 3-4 years of on site service for the device included in the deeply discounted price.
Just bought a Precision workstation at home because I could not even come close to buying the parts and a windows OS for the price I got it for.
Also bought a cheapo inspiron 15 inch laptop two years back for $149. Used it daily it works fine.
I really have a distaste in my mouth for Lenovo. Did not like their enterprise support and do not like their product, too gimmicky for me.
