"A moon base would be useless"... "Our current level of technology"... "that we could achieve presently"
Yes, a moonbase might presently be useless, but since when has technological breakthrough been at a standstill? It's not, because it happens when we're trying to achieve goals, and this is one. Advances in technology will need to occur to get a base on the moon, it's not like they're trying to put the base on the moon before they have the technology to do it.
And one other important thing: not being able to see a use for something usually says more about you, than the people who can.

How about world hunger,
There's more than enough people on this planet to have some working towards getting into space, and some working towards helping the starving. NASA aren't stopping you from helping the starving. Also, you do realise that they aren't going to be launching money into space, right? The money required to do this will stay on earth, ready to be spent on the next thing. There's no waste here on the money front.

We are talking about america here, I don't know if they have the grounds to lead the world on that front.
and advancement and encouragement of the sciences
What the hell do you think this is???
there is way too much to overcome
So we should submit to the problem rather than try overcome it? I'm glad there are people in the world who aren't as defeatist as that.

"But let's first figure out what our goals are"
The goal, in this case, is human life on mars. The moon is just a stepping stone, a warm up. During the process, we will discover, gain experience, and invent. We will learn more than what is only relevant on the moon. Sometimes you gotta take the plunge. To get life up there, we need to send life up there.
Modern FS's get around this anyway... a really simple example would be:
|-FS-|-----data-----|-FS-|-----data-----|
so each 'fs' bit contains allocation etc for the following data block, not the whole disc. This has an added extra benefit, of not needing to seek to the beginning of the disc to update FS data when making a write - just to it's own closer fs block.
The filesystem does communicate with the driver with sector numbers, but it uses its own block size for addressing, and then shifts the address to get the sector number.
"The operating system does/should not "know" anything about how the data is physically stored by a device"
You're talking about LBA, but that only applies to cylinders/heads. The OS does map to the sector (eg, file inode stored at sector 12345 from the partition beginning, which says that file begins on sector 23123 etc). If it didn't use sectors, it would need an extra 7 bits to store the location of everything within the filesystem.
The filesystem also communicates with the driver using sector numbers. It's only when you reach the 'file' abstraction level (either IO calls or memory mapped) that you switch to using bytes.
Although modern FS's will share a block for small files (or the tails of files), I don't think they do this for the actual FS data structures, which I'd guess are block quantized, so they would need to be aware of the block change to make use of the rest of the sector (either storing more info per inode, or more than one inode per sector).
I won't switch to XP because on the computer, I know what I'm doing. I don't want a speech-bubble type tooltips popping up everytime anything happens, and I don't want to be asked if I'm really-really-really-sure about every slight movement I make with the mouse.

Somewhat with you on that one. If you took a modern game (and of cause, the hardware required to play it) back in time to when you were so entertained with these old games, and gave it to yourself to play, I think it'd be a different story.

That definitely adds to their case... they need to sort out the basic service before offering new ones - if anything, for pure marketting reasons. If they released this service in india under those conditions, it would become known for it. If they sorted out the 28day thing first,/then/ released the service, it would become known as the new service without the bad name that it would have otherwise.
It doesn't seem that complicated to me.

"Dear paypal. There are people living outside UK and US"
yeah, there are also people living INSIDE uk/us/canada, what's your point?
Aside from the "under no obligation to offer a service" issue, do you have any idea how much work's involved in rolling out a service, worldwide, that's reliant on each different network operator in each country, all at once? Especially with the required security in place for this kind of service?
The fact that they'd want to try it in some places, monitor it's success, tune the service, before rolling out to other countries, seems pretty reasonable to me.
And no I'm not just saying that because I live in the UK myself, I don't use paypal, and have no need for this service.
Spoofing the originating phone number could only be done from inside the carrier's network (difficult in itself, especially if you're intended to not be traceable), and someone else mentioned they do a callback to the originating number to ask for your PIN, so you'd have to be able to intercept the call and know the PIN also to do it.

Don't they read the whole track into a cacheline anyway?
Statistically speaking, on an FS that allocates whole blocks, the waste space will be the block size * half the number of files on the drive.
