THAT's better than simply taking that money and investing it into the division?
I don't know, that could just be throwing good money after bad. This isn't a software division, it's not even like their server hardware division, it's chipmaking. It's kind of a go-big-or-go-home game where your competitors -- well-funded types like, say, Intel -- can easily pour many billions of dollars into next-generation fabrication processes and equipment which will readily put any half-assed investment to shame. I don't think IBM's chip business has the customer base to make "go big" profitable, or any reasonable plan to acquire new customers, so "go home" makes a lot of sense here.
Now, the wisdom / folly of gutting the rest of IBM's various divisions is left as an exercise to the reader.
Why not just add touch to the 11" macbook and be done with it? Not that I like touch, most of the time it's a horrible idea, but it would tick most of the right boxes: size, keyboard, touch, battery life etc...
With this new iMac and its display, the Mac Pro is starting to look a bit bleaker. I actually think it starts to look a little weird.
Performance-wise, if you configure this iMac with the 4 GHz processor, you get the fastest CPU, at least 25% faster than the Mac Pro in single-threaded tasks according to this benchmark. Mac Pro still has Ivy Bridge-architecture Xeons.
And the current Mac Pro can't drive a 5K display, but it's true that it can drive up the three 4K displays.
So the Mac Pro doesn't really make sense anymore unless you need its graphics cards to support OpenCL applications, or you want the parallelism of 8 or 12 cores, or you need its ECC RAM.
Not as far as I know, but I'm not an expert.
