They are "supported". They just haven't released any that are certified with WP7.
You're after a card with high "random access performance". The Class indicator isn't relevant in this category. If you've got a card with a high class, chances are that it's random access performance is quite low as they've tuned it down to achieve high throughput. Which is why, if you're going to be replacing it, use a Class 2 or Class 4 card. Nothing greater than a class 4.

If you have no SD Card then you are more likely to send/receive data using the wirelesss network...you can't swap cards etc I find it strange that external SD Card is not supported.

Make note that although the Focus has replaceable card - there's nothing currently on the market that is supported by Microsoft, ie you won't be able to get a bigger card for a while.

No - there is no more data. MSFT posted officially that it's a performance issue. In order to deliver adequate performance only SD cards that meet certain perf specs will be accepted. The perf specs do not match any of the current "class" specifications that currently exist. In terms of user access - no requirement in the spec for user access. The fact that there are micro SD cards used by the vendor is just a cost measure - to implement some other interface to memory would be more expensive (hence some of the phones use an SD interface but have the memory soldered onboard) Why do you think there is more data to be transmitted? The onboard storage is the same - it's just that it's not user replaceable.

Apparently most of these phones use SD cards for their storage (even if soldered to the board). Some appear to be replaceable (buy you may void your warranty). You will also lose all your data as the phone creates a file system that unifies the storage across any onboard storage and the SD card. A couple of other points: no one knows what the minimum requirements for the SD card are - MS hasn't released any certifications for 3rd party micro-SD cards yet. And the phone implements the "secure" part of SD - it's encrypted. If you want to use the card somewhere else, you need an SD card reader that implements the necessary functionality to erase SD cards with the security enabled.
