What is it about the i7 in particular that makes you think it's so immensely superior in every possible usage scenario over an i5?
It's clearly faster and in my opinion, wears out slower.
I think he's noticing the massive speed boost from jumping over to a SSD.. Lol
I would buy an i7 myself though over the i5 every time. But that's OCD speaking.
There are identical SSD's fitted in both laptop and desktop.
