Half your post is about the iPhone, and nobody doubted that touchscreen wouldn't be
technologically capable, so it's not really relevant to what I said, or the conversation. We're not talking about UI development for a touchscreen, which doesn't really have a comparable technical hurdle.
Obviously, I believe Apple is capable of making a small laptop. I just said
it's impossible using a Core 2 Duo. In 3-4 years, Apple may give us a 8", perhaps 9" or 10" laptop. However, we won't be using the C2D by next year anyway. For Apple to prove me wrong, they would need to release an 8" machine within the next 12 months or so. Everyone else will move towards dual core Intel Atom processors, which are coming in a few months.
Apple has never proven to be the best at dealing with heat issues. Their smallest laptop right now is the MBA, and it's no thinner than some 12" or 11" models out there. Those models use a C2D at around 1.2 GHz. Since the MBA's 1.6 GHz cpu actually runs at 1.2 GHz the large majority of the time, lets say the processor technology they use are all equal.
- Sony has the incredible 11" Vaio Tz that's less than 1" thick, and it has a C2D processor running at 1.2 Ghz (which is what Apple's MBA is running at most of the time.
- Toshiba has the
12" R500 model with the 1.2 Ghz C2D. It is 0.77" thick, has a DVD burner, and is lighter than the MBA. It also has a lot of ports.
- Asus has something similar.
- Same with Lenovo.
- Fujitsu is famous for their small machines.
- Apple gave people a 13.3" laptop that's essentially the same thickness as its competition (just thinner on one end), 1-2 ports, and no DVD burner. Apple's engineers would wimper if they were asked to put a DVD drive in there as well. Where would the heat go?
However, nobody has created a laptop with a C2D that's smaller than 11", and Apple can barely make a 13" mobile laptop with that chip. Don't get me wrong though. I love the MBA, don't think it's too expensive (since competing ultra-thin mobiles are much more expensive), and is light and portable. However, you said Apple was the best at handling this. They're clearly not.
