No the N810 doesn't come with a micro to mini SD adapter. You can go on ebay and find them ( ~ $0.99 + shipping ) or SanDisk sells a 1 GB micro SD kit that comes with one ~ $20 at Staples, Officemax, etc.

Here's my understanding of the situation, based on another thread <http://www.internettablettalk.com/forums/showthread.php?t=11695>;

The N810 takes miniSD cards; you can use microSD cards with an adapter.

The adapters are functional with BOTH SD and SDHC cards - there is no difference between adapters (they just change the size/shape from micro to mini/regular).

The N810 can use both SD- and SDHC-format cards (but in mini and, with adapter, micro size - no full size cards).

While my N810 hasn't arrived yet (developers delay list ), I don't believe there are any card adapters included. Look on the link above to find stores that sell adapters. They're cheap, and can convert microSD to mini, full-size, and even Sony MemoryStick Duo. And, you can convert full-size SD to Compact Flash. That should cover everything!

Hope that helps. It sure helped me.

Having been buying a mix of Sd to microSD cards for a couple of years here's some pointers for us 810 owners:
1. It seems the market for SDHC is jumping from SD to microSD, only a few mfg.'s are making miniSDHC, SanDisk is skipping it.

2. Several mfg's sell complete "kits" with microSD, includes adapters for mini and standard

3. Keep a small pair of pliers (like on my Swiss Army geek knife) or tweezers to pull out the adapters, saves inventive cursing.

4. Look for the BUY's. Right now 4GB micro's and miniSDHC's are going for $50 up. Buy.com has a 4GB mini on sale for $24 with free shipping. I just bought two more because I am presently FILLING my first one with maps for MaemoMapper. The only reason I limited myself to one the first time was to make sure they worked with my 810.

5. Look for buys - they seem to be cyclical, but within a month from the time you start looking the cycle will go thru and you will find some half off deals.

Now I'm looking for getting a nice 2.5" 1 TB external hooked up

Everyone, post links to adapters (micro-to-mini + mini-to-SD) that you find for sale in this thread. It won't be fun to always switch between micro cards with one adapter.

WFT: The simple answer is:
- The N810 can use _any_ capacity micro- or mini SD you can find.
- It'll need a micro-to-mini adapter for micro cards. One size (er, type) fits all here.

I probably am making too much out of this but it is more of a problem with my communication of the issue. My research shows that you cannot load a micro card that is SDHC (i.e., greater than 2 GB) into an mini SD adapter (non-SDHC). If that is true, you could not use a micro card greater than 2 GB which seems to make no sense. So it boils down to whether a micro SDHC can be used in a mini SD adapter? Right now I only have a 2 GB micro so I cannot make this determination.

The adaptor is just pins and wires, SDHC has to do with the addressing scheme, not the pinout.

Great, thanks for the answer. Had I just been more clear initially I could have saved everyone all the posts.
