HDTV is still lower resolution than normal movie film. (It's higher resolution than some of the digital projectors being used in theaters, though, which is why you'll notice compression artifacts in digital theaters.)
Display resolution cannot cause compression artifacts.
Just because they release it on a new format does not mean that your copy is degraded in any way. Keep the old copy in good condition. It will look and sound as good as it always did.
If you really need to upgrade, sell your old copy on ebay. That will subsidize your purchase.
I am not talking anything about analog recordings at the moment.
Let's take CD's for example. My point is that if you are going to be reproducing a 22khz sound, sampled at 44kHz, you only have two samples to account for any given cycle. That means when you look at the waveform, it is just a straight line. From what I understand of sound (I am no expert), what makes sounds different at the same frequency is the shape of the waveform.
Therefore the more samples you have per cycle, the better you are able to reproduce the unique shape of a waveform and the more real it sounds.
On a CD there is no way you could tell a sawtooth wave from a square wave from a sine wave at 22kHz, since there is not enough sample points in a cycle.
There are plenty of 96 kHz sampling systems, which will perfectly reproduce sound up to 48 kHz
I don't disagree with the bulk of what you said. However, saying that you can perfectly reproduce sound as the frequency reaches the upper limits seems wrong. What does your 48kHz sound wave look look like with only two sample points per cycle?
I know it is kind of silly to be talking about the acurracy of sound in this frequency, but I think it may be more informative to say that a 96kHz sampling rate is enough to give good sound quality in the range of human hearing (5-6 samples per sound wave, minimum).
Then again, I'm not an audio geek, so tell me where I'm wrong.
Now with new digital media, we may find ourselves having to change formats every 6 months!
Fortunately, if you have open formats, new products can easily provide backward compatibility with old formats.
Computers are smaller and faster every year. I don't think it will be too long before we have a portable player that supports format decoding plugins (like Winamp).

It would have made economic sense to support Vorbis instead of AAC because Vorbis has no licensing fees. There is nothing preventing anyone from putting a DRM wrapper around Vorbis data, if they really want to.
While the number of people that have music collections in Ogg Vorbis format is small, the number of people with AAC files before iTMS was even smaller.
You have to remember, that Apple didn't steal the market from MS. Even though MS laid out the infrastructure for digital music, they don't have a music store.
You say that MS's efforts to win the [purchased and drm'ed] digital music market with wma have failed. But in reality, they haven't started yet.
if I've just tossed 20 heads in a row, then the next toss has a strong probability of being tails -- is just plain false
Of course it is false! If you threw 20 heads in a row, I'd say the chances are great that you would continue to throw heads, since it is far more likely that you have a biased coin than anything else.:-)
But I don't mean to belittle you, and I agree with your points (which too many people have misunderstood).
Our average ADSL customer uses less than 200MB of transfer each month.
We have a contractual limitation of 10GB/month. That's just over 32kbps averaged across the month.
Yeah, but isn't one of the main selling points of broadband that you can access all sorts of multimedia?
Just listening to a typical shoutcast stream (128 kbs) for 4 hours will be over your average user's monthly transfer.
As long an isp defines transfer limits in advance, I'm fine with it. It's the ambiguous acceptable use clauses that are frustrating. How is a customer supposed to know what level of service he is really getting?
You might as well throw in some internet radio too. An acceptable quality stream (128 kb/s) will take up 58MB / hour. Even if you only listen to it for 4 hours a day (which seems reasonable for background music), it is almost 7 GB a month.
Also, if you happen to actually want to watch streaming video, which is often at 300 kb/s on the web, you will burn through 135 MB/hour.
One of the most hyped benefits of broadband was access to all kinds of media. However, if you actually use it, you definately run the risk of violating their subjective aceptable use clause.
There seem to be a lot of codecs that can get similar or better quality.
I would love to see more open formats like MPEG4, Speex, or Vorbis used. And if we can use patent-free formats, all the better.
I appreciate being able to hear audio content published on the web using RealPlayer 8 (in linux), but consumers would benefit much more from the use of open standards.
Yes, generally the GPL is about distribution. But a reason that free software may want some sort of use licence is to provide the 'no warranty' clause.
They might not compete in your view because they actually *create* markets
That was my point.
A lot of the excitement for the mini ipod was in the rumored price. At $100, the music player would definately hit the mainstream. Everyone would have one. Right now, even though iPods are the best selling mp3 player and they definately have a successful product, there are relatively few people that own them.
I guess the thing to remember is that Apple isn't in the habit of competing for the low end of most things.
Most people already seem to claim that the iPod works really well in their pockets. This new player seems to try to fill an even smaller niche than the original.
Better battery life would be most welcome. I was amazed that the newer CD/Mp3 players can get 35+ hours of battery life on 2 AA batteries (probably about 2000 mA hours). It is hard for me to belive that a cd drive uses less power than a mini hard drive.
I was thinking that it might be likely that they would release a 1.5-2 gig player in the $200 range. This would directly compete against the Rio Nitrus and iRiver's offering.
But now I see that apple is continuing the trend of not really competing with what is there. They are creating premium products, charging premium prices, and hoping that the market will be there.
The difference is that you/watch/ Scarface, but you/participate in/ Vice City. You don't watch the fictional leader bash in someone's head with a baseball bat (switching movies), you choose to do it yourself, and that's where the battle-line is: Do we allow or prohibit people from living out fantasies inside a computer game?
If the answer is yes, then we will have to prohibit people from writing offensive fiction or screenplays. After all, someone has to participate in creating it, or it wouldn't exist.
Some of us have the ability to do two things at once, considering the fact that driving is a rather simple mental process, books should be outlawed too if laptops are, I see lots of people reading books on the road, and it takes more concentration for me to read in my car than glance over at mapquest on laptop.
I'm sure glad I'm not driving the same roads as you are. Anybody that drives while reading is severely endangering those around them.
Even if driving is a simple mental process, most of the task is in observation. You must observe people swerving into your lane, people slamming on the brakes ahead of you, etc.
The most important thing is to keep your eyes busy with the traffic, not other tasks.
Talking on the cell phone is about as distracting to me as talking to any passenger (not a lot). The only times I consider the cell phone dangerous is when I have to dial or look to see who is calling. In these situations, I put the phone in my field of vision so that looking at it is similar to looking at the car's instruments. I also do not keep my focus on the phone for more than 1 second at a time.
I've also had a laptop in the car with mapping software. If you want to use it for this purpose, please mount it as high and as close to the normal field of vision as possible. That will make it much faster to glance and get the information you need.
I was mulling over how to go about building one myself, and what chance I'd have of convincing my girlfriend that while yes, we do have 3 PCs
between 3 of us
Ok, so is it you or your girlfriend that has multiple personalities?
Or maybe the girlfriend is also just one of these personalities?:)
Of course we can install all this software ourselves. But my mother can't. The reason for using any Linux distribution is to have a maximum of useful and well configured software with minimum efforts.
Sure there are software tools out there to do all the tasks listed, but are they easy to use fullscreen with a remote? Easy configuration is important, but I hope that this distribution does more than just bundle some destop-based apps.

Wow, I can see how that is "Informative". ;)
No, really. It ought to be quite a dramatic cinematic event too, considering that even R2D2 has 10 times the vocal range as the wooky?

Remember that audio cds are created in raw mode. Uncompressed audio takes 176400 bytes a second, which for 74 minutes comes out to 747 MB.
Until you look at the prices for a typical mini-itx case.
I hope the mini-itx format becomes much more popular. We need more competition in the tiny case area.
Any good sources of reasonably priced cases?
The only one that got processed was "Slashdot Effect".
1x cd-roms transfer 150 kilo BYTES a second, not bits.
Remember that a typical mp3 (which is compressed) is 128-196 kilobits a second.
