Not sure if he's running 1x16GB or 2x8GB; you can do either (the second slot is under the battery cover).

2) Which card would you suggest? What about something like this:

There's some info about where some cards won't go into a low-power state when not writing, and drain the battery in less than 48 hours of idle, but I'm not sure where, search around for it. There's no conclusive table, just some people's reports of which cards worked and didn't for them.

That issue aside, any SD or SDHC card will work. You may want to jump for a Class 6 card instead of that Class 4, but either will work. (Some people say they can't tell the difference from 4 to 6 in actual usage, some say they can; I don't have any Class 4, so I can't say, but my Class 6 cards are much faster than a Class 2 I have, so I think so.)

I am not planning to buy from them, just want to know if a Class 4 card would be good enough, or better choose a Class 6.

Thanks,

Wow... now that's bad!

I see. Is there some limit on the card capacity?

Another question (sorry!): I want to use the tablet to clean my camera CF card, sending all the images on the CF card into my 64GB pen drive. So, I should need an adapter (female USB -> male micro USB), first to save the images in the CF into the tablet (I already have a CF -> male USB adapter), and then to save from the tablet to the pen drive. Will this work?

Thanks!!

I expect the USB ports on the tablets don't provide enough power to run a CompactFlash reader. That's just a guess, but others in the fora have reported difficulty locating SD card readers that sip little enough juice. I can't imagine CF readers use less power than their SD brethren.

No, any available capacity (up to 32GB, right now) will work, and if any larger SDHC-compatible cards become available, they'll work too.

As sjgadsby said, power is likely to be an issue; if you have a self-powered USB hub, you can probably make it work fine, and even connect them both and copy directly. (This may not actually go faster, but will be easier and not need free space on the tablet.)

Also, depending on your camera, you may be able to hook it up via USB, and read the CF while it's in the camera; if this works, the camera will probably be using its own battery, so you wouldn't have power problems.

Perfect!

For the pen drive, for the CF reader, or for both?

It should be twice as fast, since I will be saving 1 step: CF card --> pen drive instead of CF --> tablet --> pen drive.

Good idea, that will solve the CF issue (but not the pen drive issue).

I wonder why camera manufacturers don't make cameras able to plug a pen drive on them. It shouldn't be that hard.

Thanks,

Chiefly the CF, most (but not quite all!) USB drives work fine.

But the tablet still has to handle all the data in and out via USB, and I expect the CPU processing to drive the USB (not the USB bandwidth itself, or the speed of either device) will be the critical factor. All depends on your device speeds, of course, and I don't think I've ever actually tried copying between two USB devices, but that's my guess.
