  1. Re:books vs. ebooks on German Book Publishers Cool To E-Book Market · · Score: 1

    You totally missed the point. The reason ebooks have become popular in the market is because of this technology which removes the main reason people have not liked reading books electronically. Prior to this, EVERY SINGLE ONE of the things you mentioned already existed for ebooks.

    No, I specifically addressed this point. Even ignoring e-ink, the technology for comfortable ebook display on laptops was not there until recently. Small cheap laptops, PDF software supporting subpixel antialiasing, and widespread availability of ebooks on the scale of google books are all recent developments that just happen to coincide temporally with the development of e-ink.

    And perhaps that is it then? You are one of the few who can spend hours reading an LCD ebook after working a desk job doing the same without it effecting your eyes? I am pretty sure that is not the rule?

    I have excellent LCD monitors at home and work and could not fathom it without getting bad migraines.

    Almost everything I stated about LCDs being acceptable for ebooks was based on the use of small cheap LCDs, so for you to turn around and refer to "desk job", "LCD monitors", and other desk-bound devices is rather missing the point on your part.

    Any technology that does not have this [e-ink] is simply a non-starter for most people. This is the SINGLE feature has allowed the ebook revolution to begin, period.

    It looks like we'll have to agree to disagree on this one. I love e-ink as much as the next person but it is NOT the most important feature of e-books. It's not even fourth or fifth on the list. You can get all of the paper-friendly advantages of e-ink just by ... printing the book out on paper. Printers are old technology.

    The ebook revolution coincides with e-ink in terms of timing, but that's just because it took computers this long to catch up to the point where ebooks are becoming useful. Before a couple of years ago, google books did not have every book, laptops were bulky and heavy, disk space was more expensive, and of course less content was available. I should also mention, though, that if you consider niche categories like academic publishing, rather than the mass market, electronic journals already became dominant several years ago, because PDFs are so vastly superior to paper for research work.

    I've used both eink and LCDs. I have average eyes (neither great nor poor). I find backlit LCDs perfectly acceptable. Most of the eyestrain from LCDs comes from the low resolution of monitors, and from sitting upright at a desktop staring straight at a fixed location for hours on end. The low resolution is greatly mitigated by subpixel antialiasing (which some people apparently hate, although I cannot for the life of me understand why anyone would hate it). Get a PDF reader that supports subpixel antialiasing for fonts. Couple that with a book-sized laptop (again, only recently available) and there's no great visual advantage to e-ink displays. E-ink of course wins on battery life, but backlighting has its advantages too; for example, it's easier to read in the dark, or in low light.

  3. books vs. ebooks on German Book Publishers Cool To E-Book Market · · Score: 2, Interesting
    The whole dichotomy over printed books vs. ebooks just seems strange. You don't have to choose one or the other, you can have both. And you don't need a special ebook device; most of the key benefits of electronic books are available on an ordinary laptop with a PDF reader.

    This is, of course, assuming that the publishers and lobbyists get it right, and don't destroy the entire product category out of greed.

    Advantages of ebooks that you will never get in a printed book:

    • Text search. This is especially important in academics and research. You want to find where a phrase is defined and you don't want to read the whole book to find it. An index is a far inferior alternative.
    • Did I mention search? Well, it's not limited to just one book. You can go online to google books and search for a phrase in every book ever published. This achievement is stunning when you think about it. The fact that publishers seem determined to kill this golden goose with their greed is pretty depressing.
    • Portability. Sure, if you have one single book vs. one Kindle, the comparison is pretty favorable towards the book. But a Kindle can hold several hundred books, and a laptop can hold tens of thousands. When traveling, it's not even a question of books vs. ebooks, since 10000 printed books are physically impossible to carry with you. Oh, and of course, you can perform text search across all those books too.
    • Ease of copying and backup. The publishers hate this one, and try to do everything they can to prevent it, but for the user it's a boon.

    Of course, printed books have advantages too: higher resolution, low tech, can read in bathtub, doesn't matter as much if you lose one. So there is room for both formats in this world. What would make sense is for publishers to automatically supply the electronic rights to anyone who purchases a physical volume. That would greatly increase the value proposition in a book purchase, and (dare I say) expand their market and profits. It's frustrating that everyone except the publishers themselves seems to realize this.

    Well, that last bit has an important and noteworthy exception. In academic publishing (journals and such), it is the norm rather than the exception for publishers to provide electronic rights to libraries and institutions that purchase the corresponding physical copy. So there is hope that the rest of the industry can come to their senses in time.

    It's worth mentioning that technological progress (if not stymied by the copyright lobby) will eventually bring to ebooks all the advantages of printed books, whereas no amount of progress (short of replacing books with ebooks) will allow printed books to compete with the advantages of ebooks. The resolution of ebooks will improve, and it is at least conceivable that they can be engineered to last months on a single battery charge, or be waterproof, or become cheap enough that you wouldn't mind losing the hardware (the content will, of course, be easy to back up, once the DRM fetish subsides). So, for now, we have a choice of printed books vs. ebooks, but in the future I see ebooks taking over.

    Thanks for your response. Actually, I basically agree with everything that you said (well, if not agree, I can at least understand your viewpoint).

    Everything, that is, except for the GST.

    The GST is an enormous contradiction in terms. Some of these contradictions are laid out in your very post which I am replying to. Let me explain.

    First of all, you say the GST is miniscule on an individual level yet provides significant funding. I have no idea what you can possibly mean by this. A miniscule tax, by definition, cannot provide significant funding. Taxes are measured in numbers which have magnitude. A number cannot be simultaneously large and small.

    Perhaps you mean to say that the GST is imperceptible to taxpayers, yet provides significant funding. This is actually very true, and in my view it is a huge reason why GSTs/VATs are destructive. They are essentially a way of deceiving the population about how much taxes they are paying. The argument that "GST/VAT is deceptively perceived as a small amount relative to the amount of money it actually raises" is to me one of the biggest problems with GST. I dislike policy proposals that exploit public deception.

    The other thing that Canadians need to decide is whether they want a tax policy that is progressive or regressive. Your post mentions transfer payments, something which is inherently progressive, and further evidence is provided by the income tax code, which in Canada is far more progressive than in the US, approaching levels only seen in northern European countries. Yet the GST is without question strongly regressive. Contrary to your assertion that the GST only affects the "very rich", it is in fact the poor people who are most harmed by GST. Don't believe me? Think of the GST as a 5% flat tax on consumption (which it is). Now consider the fact that poor people spend a greater percentage of their incomes on consumption than rich people (which they do). It follows, mathematically, that poor people pay a larger percentage of their incomes to GST than rich people. That's right, the GST is worse than a flat tax. At least with a 5% flat tax, all individuals, rich or poor, would be paying 5% of their incomes.

    Yes, I know, there is a so-called "GST/HST tax credit", but it has no relationship whatsoever to GST, does not depend in any way on the amount of GST that you actually paid, and IMO the linking of this tax credit to the GST is in and of itself a political deception. As proof, I point out that the Earned Income Credit in the US, which operates in exactly the same way, has nothing to do with GST, as indeed the US has no GST.
