My First question would be what are you using it for ?
To warrant such a high spec ?
Thats a lot of money to throw at a Windows 8 machine !
That little bit that says i7 is where the wonga is.
And the Touch screen.
External storage : Just use drop box / Google Drive
Most laptops now run on SSD Drives.
Solid state drive no moving parts = quicker.
Touch Screen Note:
Think about this, most people hate to sit with a laptop and see smudges on there screen, and when they do see them want to clean them, so that's what we do.
Well 5 mins using a touch screen with greasy fingers get your cloth ready as you will always be cleaning it.
