Which of these do you recommend?

Phone contract runs out very soon and looking to start a new contract with a laptop as the free gift.

Wanting something powerful but unsure whether the highest end laptops on the site are worth the extra pay.

Looking to spend no more than £30 a month on the contract. The details (such as minutes per month and texts per month) aren't too important.

Had my eye on the Dell laptop - would that be a good choice? I know that the site is legitimate (have bought two phones previously on similar deals and received cashback and an 250gb xbox 360 from previous contracts).

Quick feedback would be much appreciated!

Thanks a lot!

There are a lot of personal variables to take into account, so this is something you shouldn't need our help for.

I have changed my mind on what I am going to do:

I am instead going to go onto a cheaper contract (£20 a month) which gives me £220 cashback. With the money I'm going to invest in a powerful laptop, somewhere between £200-£350.

It is now potentially between these:

http://www.ebuyer.com/product/257135 £329 i3 2.4Ghz

Being unsure of which of these would be ideal, I venture back for assistance. My usage will vary, even I don't know what I will use it for, but by knowing the pros and cons of each system (they are all pretty similar bar the processing unit) I would be more confident with my choice.

I'm swaying towards the i3 because it isn't a huge step up from the other models but I believe it will be a better choice in the long run. I don't know though, help would be much appreciated!
