    Um, no.

    Market share and install base are definitely linked. If Apple's only selling 3% of computers, their install base is going to trend to 3% over time, holding all other things equal.

    Mathematical example: total market is 100 computers, Apple has 3% market share)
    Year 0: 6 Macs, 150 PCs (so Apple has about 3.8% of the install base when we start)
    Year 1: 9 Macs, 247 PCs (install base is 3.5%)
    Year 2: 12 Macs, 344 PCs (install base is 3.3%)
    Year 3: 15 Macs, 441 PCs (install base is 3.2%)

    I think you get the picture. Market share is not representative of total install base RIGHT NOW, but is certainly a good indicator of what's going to happen in the future. If you disagree, that's too bad, because I've just mathematically shown that you're wrong. Market share and install base are definitely linked.[1]

    Apple's profitability really has nothing to do with their install base so much as their margins. If I'm selling stuff with a huge mark-up on actual costs, I could sell 30 pieces of it and still make money, even if the total market is 3 billion pieces.

    [1] As for your "PCs don't last as long as Macs": prove it. I've used Macs for years, and Apple's build quality is not as good as people make it out to be. I'm not going to factor in differing "computer decays" without any kind of proof for them.

  4. Re:How about custom duty on software from India? on Illinois Considers Taxing Custom Software · · Score: 1

    I'm not certain a national sales tax is a good idea. At all. And I say this as guy who's pretty much done (one course left!) with a degree in economics, so I'm not talking totally out of my ass.

    The problems with national a sales tax:
    1. People who were at the lowest tax bracket (aka, poor people and a LOT of senior citizens) weren't paying any income taxes to begin with, and thus this becomes a tax _increase_. The position paper they cite talks about rebates, but I can't believe there's any sane way to audit that.
    2. It raises the price of goods, and makes people less likely to consume, thereby hurting businesses (and hurting the people they employ). You could make a similar argument for income tax, certainly, but it's an issue of mental framing. Once you've paid income tax, that money is "yours". But when you pay a sales tax over and over, it feels like the government is artificially raising prices (which, of course, they are).

    Social security is going to collapse, and I do feel some animosity in having to pay for something I'm never going to see (I'm 22 years old). However, I'm not sure how import taxes are the solution to saving it.

    I agree. I make it a point to NOT try to get out of jury duty, and I think of myself as a fairly intelligent person. Maybe if people took their societal obligations more seriously, and didn't subscribe to the idea of "getting out of jury duty is a good thing", we'd have fairer courts.

    There is some blame to be laid on the system for pulling in 400 people for duty and only using 12*(3 to 6) of them, though. Jury duty is often perceived as a waste of time because of that. What we really need is to remove the BS pre-emptory strikes system that leads to racial/gender bias in the jury box.

    You bring up an excellent point, which is the importance of _sustained_ growth.

    A few years of 7% growth is amazing, but it's not all that great in the long run if your growth rate bottoms out to .1% for the next 20. The US has averaged about 1.5% growth per year over the history of the country - and slow but steady wins the race.

    The fact that (whatever country) is growing at 10% this year is no indication it will continue to grow at 10% forever. I believe that most /.'ers lose track of this simple fact. Often, there are societal, legal, or cultural reasons which will end up slowing down growth (trade restrictions, for instance).

    The fact that Europe is "getting stronger" in the GDP department is not something to be worried about - since we have (mostly) free trade with the EU, their strengths can fill our weaknesses, and vica versa. Everyone's standard of life in the US and Europe will (hopefully) go up.

    However, I would caution against misinterpreting the EU expansion with actual growth. In one sense, all that's happening is Europe transferring money from their left pocket to their right pocket. What matters over the long run is real growth, and (unfortunately!) there have been some problems with that.

    "To properly review a distribution probably takes longer than most people who do such reviewing have time for."

    Amen. Most distribution "reviews" are one page praise pieces these days, written by people who honestly have no qualifications in the first place to write a distribution review.

    Could you imagine reviewing Windows, Office Super-Deluxe, and a hundred other bits of major software in a _day_? Of course not. You'd have to spend WEEKS. Yet, lo and behold, the majority of idiot reviewers do the install on a single machine, blame the distro for anything that goes wrong, and then go nitpicking (or, alternatively, ignore all flaws and praise the distro anyways because they use it). What happened to the rest of the damned review?

    I'd also like to see some relatively unbiased reviews. For the love of G-d, please do not write a review if you're in love with the system in the first place, because you use it on your personal box. It just ends up as a piece of evangelism that wastes the three minutes of my precious life.

    To summarize:
    1. Limit the scope of the review to:
    A. Certain users (and do proper and formal usability tests with them).
    B. Certain pieces of software within the distribution (but be certain to test them thoroughly!). If this means you limit it to the installer and certain generic OS tasks, than so be it.
    2. Make sure you are _qualified_ to write the review. This should involve some formal educational background in usability engineering at the very least. No one's interested in uninformed opinions.
    3. Don't review the distribution you use and love. Your review will be hideously biased, whether you try to make it fair or not. Example: This is the primary reason why all Gentoo reviews seem to gloss over the horrifying install (in my experience).
    4. On a similar note, give every distro a fair shake. The fact that it doesn't work just like your favorite distribution should not be a point against it. I'm sick and tired of hearing "but it doesn't have apt-get, so it sucks".
    5. Avoid absolutes such as "this is the best" or "this is the worst". Make note of pros and cons, and let the reader decide. You can give recommendations if you want.
    6. If you alter the system by installing non-standard software, make note of this (ie, apt on Fedora or SuSE). If you're doing weird configuration, make note of it on the review, too.
    7. Thoroughly inform yourself of the features of the distribution, and make note of the fact that you're not reviewing the distribution on 1000 machines at once (if the distribution was intended to scale like that). Example: This is the primary reason why RHN always seems to get bashed in RHEL reviews - people make believe it's just up2date, and miss the extremely useful remote management functionality.
    8. Avoid getting into comparison situations. If it's hard to install software, say so, but don't damn Mandrake for not being Slackware (or vica versa).

    Those are some things to look for, anyways. Like I said, too many idiots taking too short a time to review far too much.

That's not to say education is worthless (far from it!), but that it has difficulty justifying its own costs.
