I didn't say they weren't mutually intelligible. I just said they are different, which they are. Spelling is different. Pronunciation is different. Certain words are different (and not just slang words), as are certain grammatical rules.
We do have different accents in the US, but the differences aren't as great as the difference between American English and British English in general. As for Siri, I was a little surprised that they included Australian English but not Canadian English, but the more I think of it, at the spoken level there isn't much difference from American English (it's mostly at the written level). Perhaps as it matures, Siri will add an "International English" along with Indian English.
I know that, i'm not saying it's the same, but it is easier to do a port from American English and British english than make siri compatible with Portuguese. But, as you see improvements in both voice recognition service, you can't see any information about siri available in other languages.
Actually, in all the TV advertising I've seen here in the US, there is never a mention of LTE. The only feature ever mentioned is the Retina Display. The wireless capabilities are mentioned primarily on the website, fairly low down the page. Most iPads sold are Wi-Fi-only models.
Even the rumor sites the day before were suggesting that the international version might not ship with LTE support of any kind.
That said, Apple should have made the websites clearer at launch. I see now that they have fixed the pages. See the link to the UK site below. The wireless capabilities are still improved over the last version (faster support for HSPA+ and DC-HSDPA).

Yes, you are right, they made several changes in their website as I can se now in portuguese apple. Before they were REALLY advertising the new iPad as 4G compatible, now it has changed to HSPA, HSPA+ e DC-HSDPA.
It might not be that simple. I looked at Vodafone's German website and saw only a single LTE-compatible device (an HTC Android phone). It's entirely possible Apple isn't able to get the chipsets in sufficient volume or yield. This is their first LTE device of any kind. If they are ordering a bunch of European-compatible LTE chipsets, my guess is that they are being allocated to the upcoming iPhone, which is far more important to Apple's profits than the iPad right now.

As you can see here http://www.tmn.pt/4g/#cobertura
Portugal have LTE support, and by the end of the year will be available to all country. I know that we are small, but still.
And TMN do offer support for Galaxy S2 and Galaxy Tab.
Unfortunately, LTE support is complicated. Even in the US, for once the carriers all agreed on the same air-to-ground transmission standard, but they all have different, non-overlapping spectrum. Apple will need to support 4 LTE frequencies just to get coverage on all of AT&T, Verizon, and Sprint's respective networks. Europe adds 3 more non-overlapping bands.
It's not just Apple. According to the Global Mobile Suppliers Association, a plurality of LTE devices are designed around the 700MHz spectrum, because of the pace of LTE adoption in North America.
Interestingly, the UK regulator is considering allocating the 700MHz spectrum to LTE, partly because of its wide scale acceptance in the US.
Thats other thing funny in the USA, you like to be different. As the rest of the world uses the metric system, you use the imperial system
800mhz has a better performance, better penetration, causing better reception indoor.
But stil...
The point is just that Apple don't support Siri outside USA, don't support other LTE bands, crap iTunes store in some countries etc etc...
But we still love them, don't we?
