Laptop Choice

A quick question for all you hardware gurus: if you had a choice between three laptops that were pretty much identical in terms of graphics, HDD, RAM etc, which of these three would you go for:

1. Toshiba with Intel Core i3 2328M 2.2GHz
2. Lenovo with Intel Pentium B970 2.3GHz (+£25 over Toshiba)
3. Acer with Intel Core i3 3110M 2.4GHz (+£49 over Toshiba)

Incidentally, the Lenovo comes with Windows 7; the other two have Windows 8.

Thanks…
