As usual people are up in arms because they can't spend their money on this toy for all the many reasons we've just seen.
As has been pointed out, this is a NEW laptop. It doesn't replace anything Apple has made so far. It fills a niche that Apple decided was worth filling. As with any product, it has an audience. People can spend their time on here complaining about anything that isn't in line with what THEY want or worse, what THEY think WE all want or worse still, what THEY think the FUTURE is. Apple spends enough time and money on research to know whether there is a target audience for this.
Now this is a forum so we all feel the need to be heard.So far there has been no real argument as to why this would in any way shape or form be a product that limits people in what they do. It is up to us to decide which laptop is best suited for our needs. Lucky for us, Apple has added a new product to its current lineup. It's new. It's foreign, it's different to anything else we had. Apple is happily selling it to whoever decides that it fits their mobile needs.
This thing is right up the alley of those who are on the run all day and have to do things you can't do on an iPad without being seriously frustrated. Those who connect to a corporate network via Citrix Client at the airport to approve purchase orders and grab the latest sales presentation or figures. Or those who run websites and have to manage them anytime from anywhere. Those who run blogs, build websites and create new ideas of pretty much anything. Heck, it even runs Xcode and it may not exactly fly when you compile your latest creation but you'd surely have your central repository on a cloud based machine that does all the hard work for you while you code away somewhere in a park under a shady tree or heaven forbid, in your local Starbucks.
Yes, the iPad has some great apps but it's an iPad and not a Laptop. This thing is totally going to fly with many, many professionals out there. Not everybody is a Video Editor and certainly not everybody needs anything hanging out of their laptops to do their job or to feel important.
I have many USB sticks and drives. But apparently the cloud is the way to go and so this laptop is based on cloud usage. It's for those who can and will put everything into the cloud or onto up to 512GB of local, fast storage and roam around the country or the world. This thing is all about being wirelessly connected to everything that is available out there in the cloud. Don't like the idea? Why not buy something else?
If you want to use OS X with all its apps and functionality and you want something even smaller than an Air that even has a retina display, then get your money out of your pocket and give it to Apple for they have just created the perfect machine for you.
If you think it's too expensive then you buy an Air. If you think you need plenty of ports, then you buy a MBP. No problem at all. There is a plethora of Apple laptops for you to pick the one that suits your ever so specific needs.
If you don't like Apple products, heck, buy a Chrome book or a surface pro. There is so much choice out there these days.
Watch the Apple presentation again. They make it very clear who they want to sell this to. I'm sorry that it's not you and I see that you may be upset because of that but the good news is that you can save your money and spend it on something else that may be more suitable for your needs.
Oh, and yes, there was SOME sarcasm in this post, too.
