The Dell you mentioned is both more powerful and more expensive. If I were you, I would suggest you consider a business laptop such as Lenovo Thinkpad, HP Elitebook, or Dell Latitude/Precision.
@rwinches, it was a voucher for 3 months of free service, not a free trial. It could be used with an existing account or be used to create a new account without billing information (trial accounts require billing information.)

I recommend HP Elitebooks. Get one with an SSD and it should last 10 years. HP's business laptops are very well built. I know HP's consumer laptops are crap, but HP's business laptops are designed completely separately and cut far fewer corners.
