Can't decided between vostro and inspiron

I am in the market for a new laptop and am definately getting a Dell.
I am replacing a Toshiba Satellite 17" and I had nothing but problems.
I can't decide between the Vostro 3700, Inspiron 17r or Inspiron 15r.


I will mainly be transporting it between home and office daily and doing work at home as well.
Vostro 3700 and Inspiron seem similar but I've heard that the vostros don't have as much entertainment possibilities? Not sure what that means.


I won't be using it for gaming, mainly editing photos (I'm a realtor), doing spreadsheets, browsing the web, etc.


Thanks!
