Earlier, in the back to school period, I discussed the benefits and costs of going paperless as a student. I think it’s a really worthwhile choice which has a lot of benefits down the line. My main concern is simply the high initial cost of converting from paper to paperless which means that it is a better option for people who are making money from doing it as a job because it will severely cut into your beer money.
I think it’s hard to talk about people going paperless in 2009 without mentioning the eBook reader, the new group of devices which are being marketed as a way to replace the printed book.
The science bit
The market has pretty much expanded from very little into the next big thing based almost entirely on the invention of a small (but growing) American company that worked out how to make very small magnetic objects reliably rise and fall in a grid pattern. Unlike the great majority of modern technology this relies on moving part because once you’ve moved the parts to where you want them you can leave them there with no extra energy use. This means that the ereader expends energy “printing” the page – putting the eInk particles where they’re supposed to be – but then doesn’t need any more to keep the text on the page.
This differs from a traditional display because earlier technologies do not create a fixed image – a CRT monitor draws images onto the screen with a scanning electron beam on a phosphor screen and an LCD monitor uses an arrangement of gates which produces a coloured filter for a backlight to shine through. That electron beam and that backlight both require continuous power to operate. The main benefit of a fleeting, dynamic way of generating images is that it can be very good for conveying moving images, whereas eInk is limited by the physical speed of the particles. That’s bad for movies but text has never moved in its life and that means the technology is good for dedicated book readers.
This is really all by to the by, because how the underlying technology works rarely affects how good it is for users.
The message to take away is simply that because it’s not a continuously operating device means that you don’t measure the battery life by how long it can be on for (because the device is only on for short spurts) but by how many times the display changes. That’s why the Sony Pocket Edition is rated as having enough “battery life for nearly 6,800 page turns.” The amount of time that is depends on how quickly you can read that number of pages.
Ebook readers have the option of, generally, being used to display books licensed from the sponsoring bookseller’s shop which is great if that’s how you buy books (it isn’t personally). I think it has great potential for updateable textbooks which apply their own errata and apply the differences between editions if that’s the way publishers want to play it. Right now I think the potential lies in the ability of these devices to display your own documents. I think the ability to load up an ereader with a load of case reports and then read that on the bus is paradigm shifting.
This has additional benefits in that because the image is static it doesn’t cause headaches from forcing people to squint at flickering displays and because there’s no backlight you aren’t forced to stare at a light.
Just because the underlying technology is well suited to displaying text this doesn’t mean that you should buy every product which uses it and displaying text on its own is something that computers have been able to do for a very long time. Ebooks readers are not the only option available here.
The obvious alternative is just a laptop – it will read any format you should care to name, runs off a battery, is portable, does more than just text and you probably already have one. It’s not ideal for reading on the bus, the LCD screen is backlit and the battery won’t last particularly long. But it does so many other things as well and it is likely to be a product that many people will already own, and that makes it practically free to use as an ebook reader.
The mobile phone
An unexpected new contender is the mobile phone, people have been using PDAs to read text for many years and the phone is converging on the same areas. These are good because they’re so much smaller and more portable and have long battery lives. On the other hand, this all depends on the quality of the screen. One of the most often recommended devices for reading books is the iPhone, which has an undeniably pretty screen, on the other hand it is an excruciatingly expensive way to read on the bus. It’s a good product and if you use it as a phoning, mobile emailing, mobile webbing, app running device then it’s really good. If you’re only using it to read Westlaw PDFs on the bus, though, the initial cost and monthly fees make it a difficult purchase.
A good photocopier costs many thousand pounds and weighs an unbelievable amount. It is beyond the dreams of any student to own. However, many facilities give you access to such a photocopier for around 3-5p a sheet. That means that you can have a 5 page report to read on the bus in black and white for about 25p, and the truly frugal student will take steps to get that price down further – by printing on both sides of page or by fitting more than one page onto each physical page. I think the photocopier is the main enemy of the ebook reader because you need to print between 3600 and 6000 pages before you would have saved money by buying Sony’s cheapest ebook reader (the Pocket PRS-300). That’s a really long term investment to save a bit of paper. I think you’d need to really need the extra advantages of the ebook reader to make it a more convincing option.
Reasons to buy right now
This is the hard thing, I don’t see a reason to buy just right now. I think the technology is extremely impressive and I think the datapad from Star Trek is nigh but at present buying one is a huge expense, particularly because you know it will get better and cheaper as time goes on. It’s hard to justify the expense when centralised photocopying exists. Once prices come down I think we’ll really reach a point where it’ll be hard to tell why you’d ever print a document out but we’re really not there yet.
The main reason to buy now is simply if you want one, it’s not long til Christmas, but I imagine this will rapidly change as prices come down (and they will).
