I think the need is for full fledged computers this size. I have tried running some CAD programs and they are useless. MAC's don't even run Rhino3d, one of my most used programs, and you cannot use them to hook up to a CNC machine or other type of automated machinery. I know there are people who never do this kind of stuff, but some people actually make objects with their computers, and as much as Micro$oft is bashed, you can run some rather expensive, $100,000 and up equipment off of them. I have never seen this done with MAC's or Netbooks, or any of these other machines that are starting to cost a real lot of money. Meanwhile, you can put a QuadCore AMD machine together for under $800 bucks that will do everything and much more than these laptops can do. I personally think the day you can start building your own laptops to your own specs could make real change. These machines are useless to me. I do own a laptop, but rarely use it. I know of those who cannot live without them.
A portable fully capable computer is what is needed. A laptop machined from "a single piece of aluminum" means nothing to me. I was a machinists for 16 years. I have made bulkheads for Blackhawk and Super Stallion Sikorsky helicopters. I do not know why this is such a big deal. I would think a Carbon fiber lightweight machine that did not conduct electricity so well would be more attractive and practical. The hard drives are too tiny is the latest Apple offering For the price, any offering from Apple or Micro$oft or other manufacturers should offer the most available technology one can packed in or the price. Any else seems like a rip off to me. Why do you need to have so many machines. This opinion does not include smart phones, of which I use very little but can see some advantages too. I just don't want to pay all that money out for the data plans. I buy tools for my machine shop with the money I save. Netbooks made sense, when they were real cheap, a cheap way to cruise the internet. Just an opinion. As far as the software, it seems like a lot of dumbing down to make it fit into a small package, dumbing down of software and people. I also abhor fingerprints on my screen.
