Core i3 lenovo vs msi or hp?

Hi im looking for a laptop to take to college in addition to my desktop.
I came upon these two laptops in office depot

14'' Lenovo thinkpad for $579.99

15.6'' MSI for 499.99

I like the size of the lenovo but the msi seems to be nicer build quality but the 14'' size of the lenovo is just perfect.
Also I configured a hp G42T on the hp web site which came out to be 549.99 but it included a 7200 rpm hard drive with similar specs.
Do any of those office depot computers come with a 7200 rpm hard drive I cant seem to find it anywhere.
Have any of you experienced lenovo laptops? I need one by the 19th which is my move in date.
