Something I'd like to see Apple sell (or any other OEM, for the record), would be a RMBP-sized laptop with a ULV CPU inside, specifically a 15W one.
You can say: "buy MBA or XPS 13 instead", fair. To that, I answer: those internals in a RMBP case would deliver much higher mattery runtimes. The higher battery runtimes, the better, if not more, because it would last more time on those 500-1000 charge cycles they are rated for nowadays.
I admit, I never used
a mac i my life. In my defense, I say that when I bought this laptop, I didn't know what I wanted and chose the cheapest 13" I found.
Now, I know. I need great keyboard, great build quality, great battery runtime and great sound system. And, despite being a Windows user, if I could find those specs on a Mac, I would jump in in a second.
Ok, enough wishing.
