Graphics, User Interfaces Samsung has developed a completely transparent solar-powered monitor that's designed to be used with ambient light. Though they're marketing it as a television, it's almost certainly going to be used initially as displays in commercial areas, and it apparently is also a touch-screen, opening it up for the coolest kind of kiosk you've ever used. See a video after the jump.

I think that paper is needed for several reasons :
-You can draw freely on it, not just write on a guided path
-It's light
-It's inexpensive
-It's easily transferable and disposable
-If you spill your cofee on a piece of paper, you only loose that piece of paper. Globally, paper is something which you don't have to care about, and can therefore more freely use. Frenzily scratching it with a bic crystal it is a valid option.
-It's the perfect medium for important letters, because using it shows that you care about the person.
-Considering the amount of security flaws which are discovered in mainstream OSs every year, do you really want to trust them to take care of your important documents ? I mean, seeing how quickly Elvis Presley was seen in an airport after biometric passports were introduced in the US should have some warning value...

Also, reading and writing is much easier on paper than on a computer screen.

- A friend just bought an Asus EP121 Win7 tablet. It's brilliant. You can easily draw with a stylus or take notes. I imagine that you can get a stylus for any of the current tablets. It's much easier to use than paper because you can erase, use different brushes and colors, layers, transparency and so on.
- Using Dropbox or a similar service you can make your documents easily transferable and furthermore accessible from anywhere. Wi-fi is widespread, mobile connectivity is reasonably cheap.
- Most people buy and carry a tablet or a laptop anyway, so there's no added cost or weight. Actually I'd say that it's easier to carry a tablet with thousands of books and documents than carrying said books and documents.
- Important letters can be electronically signed.
- You are less likely to lose your device than a piece of paper.
- You can search your local and on-line documents in seconds.
- Papers can be forged, copied or read without authorization, stolen, lost, crumbled, spilled upon, so I'm more worried about the security of keeping things on paper.

When I need to do some heavy task, I indeed take my computer (and the pen tablet attached to it), but it doesn't mean that it's easier to use than paper for note-taking or rambling purposes.

Only the "erasing" side counts a lot among what you've mentioned, in fact that's the main reason why I'd buy a tablet if they were good enough to replace paper in other respects. But the rest isn't much needed in normal circumstances, where a piece of paper and four ballpoint pens are enough.

It's a matter of using the right product for the right use. I know that today, all-in-ones devices which unsuccessfully try to be good at everything are trendy, but I prefer to stick with what's best for each job.

Introducing the notePad. A revolutionary product, at an unbelievable price.
1. Decide to give what's on a piece of paper to someone
2. Grab the sheet of paper and pull it slightly
3. Hand it to that someone

I'm sorry, but fiddling around with several apps and frenetically moving your fingers in all directions for a minute, and then asking other people to do the same in order to retrieve and use the document, just doesn't come close to the simplicity of this. Now, I agree that digital services win hands down when it comes to sharing files with lots of people, due to how easy it is to make many copies of a digital document. I heavily use e-mail for that. But for working with one or two individuals, which is what many of us do on a daily basis, paper wins.

- Most people buy and carry a tablet or a laptop anyway, so there's no added cost or weight. Actually I'd say that it's easier to carry a tablet with thousands of books and documents than carrying said books and documents.

A laptop has a significant cost in terms of used space in the backpack and weight, that's why I don't carry mine around anytime, but only when I know I will need it. If I wanted something to always carry around everywhere, I would have had to get something thinner, smaller, and lighter, but then I'd have to give up on some other desirable characteristic on my laptop (power, comfort...), which are more important to me that carrying around things which I most of the time don't actually need (which also includes thousands of books).

- Important letters can be electronically signed.

Yeah, and ? For the receiver, this means that you've taken around a second of your time to click a button in your mail client. That doesn't exactly makes him feel any more important.

- You are less likely to lose your device than a piece of paper.

But it is more likely to be stolen, and the cost in terms of lost money, time spent setting up everything, and personal data is much, much higher.

-You can search your local and on-line documents in seconds.

Don't know how I feel about this argument.

On one side it's true. For some tasks, like exploring an article's bibliography, the superiority of big online libraries and their offline copies is unchallenged. Even though it's an absolute pain to read something on a computer's screen, when you want speed and either read short documents or don't read them carefully, the benefits are much, much higher than the cost.

On the other hand, for more daily tasks, I have this principle that if you need some fast search mechanism to organize your own files, you're doing it wrong, because it means that either you organize your files very poorly or you have too much of them around compared to what you actually need. I tend to disable things like indexed searches on my computers, in order to increase performance, battery life, and storage media longevity, and I can ensure you that if the inside of your brain (as reflected by the folder hierarchy you spontaneously create) is properly organized, you really don't need that. It's valid for my uses of my computer, though, yours may be different.

- Papers can be forged

If you're talking about unprotected content, it's much easier to make a perfect-looking copy of a digital document (Ctl+C, Ctl+V) than it is to make a perfect-looking copy of a physical document. If you're talking about protected content, every single DRM which has ever been out there has been hacked within a few months or years, whereas physical protections like those which we put on money tend to last much longer.

copied or read without authorization

Like most digital content out there ;) Seriously, though, every protection has a cost. If you have some papers which you want people not to see, you put them in a safe place with a good lock, but it has a cost, and accessing them becomes harder. In the same way, you can protect digital content with things like encrypted partitions, but there's a cost: the passphrase. You have to type a password any time you turn your computer on (which increases the chance that someone will read it on your back), and thus to remember it. If it is easy to remember, it's easy to crack. Maybe biometrics are the solution on those matter, but afaik they haven't delivered so far. Plus, even in this case, nothing would prevent you from putting your paper in a case with a biometric lock.

stolen, lost

Computers can be stolen or lost. In fact, where I live, it happens regularly.

crumbled, spilled upon, so I'm more worried about the security of keeping things on paper.

Computers are, taking into account how much data they hold, much more vulnerable than paper to physical dangers, except if you have sold one of your arms to buy one of those uncomfortable and technologically dated "rugged" things which a tank is supposed to safely roll on. Plus, digital storage media tend to have a pretty short life even when they are taken care of, as compared to books which can survive for around a century, more if they are built to last, which means that they require the hassle of frequent backups to be reliable.
