thanks. i guess most chings here will suggest t540p
as i am looking for a refurbished one for my wife only, i may not wait for 2015 models
indeed, t540p is more expensive (~$500) than inspiron 15 but spec is a bit weaker...
8gb ram vs 12gb ram
500gb hdd vs 1tb hdd
non touch screen vs touch screen
but i want to find a reliable laptop for my wife to work at home, so i guess i will choose t540p too
