This might be a question about Android architecture, or it might be specific to Asus's semantics. I'm planning to buy an Asus TF101 Eee Pad, the Transformer. "RAM" is 1 GB, and "Storage" options are 16GB or 32GB.
Being one who believes that "it's better to have it and not need it than to need it and not have it" I'm inclined to pay for (and possibly wait for) the 32GB option. However, there is a micro SD slot - for adding another, external, DASD. There's also an SD slot in the keyboard dock.
My question: what are the functional differences, if any, between the storage added via the SD slots and the storage that comes with the unit originally?
This is basic Android functionality--there are many apps you can't (yet) move off of the device's internal storage onto an SD card. You can't move anything with a widget to an SD card and have the widget work. You can move other apps to the SD card and have them be fine, however if you turn your device off, when you turn it back on it will take a minute or two for those apps to become available as the device reads what is on the SD card.
Some devices with larger internal storage partition it so that part of the storage functions similarly to an SD card, as well.
Music, ebooks, etc, can all be put onto an SD card with only that slight initial delay as the unit reads the SD card--I have my music and ebooks on my Evo 4g on an SD card and experience no problems from that standpoint.
So, your biggest limitation will be apps which can't be moved, in my experience/opinion. Personally, I think 16 would be fine, but I would probably weigh the cost of the SD cards against the cost of bumping up the device before buying.

yeah, I'm awaiting the information myself =) it's likely that'll be my next new toy as well, though I am also keeping an eye out on the Toshiba tablet and whatever other contenders may come out between now and when I am able to get mine!

Onboard storage in honeycomb is dynamic, meaning you could fill up the 16 or 32gb of memory with apps if you wanted to and just use the microSD slot for storage. You can have any mix of apps and storage and it doesn't matter. Not like on 2.3 or earlier where it's fixed based off of the 256, 512 or 1gb of ram they offer. Makes the apps2SD thing kind of moot because I'd rather keep everything app wise on board if possible and use the card slot for pure storage so that nothing is effected if I swap cards for some reason or another.
