I suppose any Android based device can, but none of these seem to have any real storage space!
You can get photobank devices that are basically portable hard drives with inbuilt card readers that will transfer any file on the card to the hard drive, but they(or the good ones) are quite expensive!
That is, a basic USB host capable tablet + cheap portable hard drive combo will usually cost you less(approx $400, if you shop right).
You can use the tablet as a browsing device and for any other purpose you deem appropriate.
For transferring iamges, you'd connect a USB hub to the tablet and then connect both the camera and external hdd to the tablet via the USB hub. Find all the images on the camera and transfer them to the external hdd.
Note that not all cameras support the Mass Storage device protocol any longer, so the camera connected to an Android device
may not show up as another external card .. which is what is supposed to happen.
I'm yet to acquire a USB port/card reader device for my table yet, so I have no idea if this WILL work for me ...... yet!
For this process tho, I do have my Win7 tablet if I ever need any external storage space for my images .. and this system is not only foolproof but is my preferred system.
A Win7 tablet(Gigabyte) cost me just under $700 and no other devices or peripherals were needed, and it came with a 320Gig hdd... so in a way, is (almost)ideal as an image bank.
There are probably other solutions to this age old problem, but they tend to cost quite some money. I accepted this as an issue to be dealt with, rather than procrastinate over it due to the cost factor.
So my preference(s) then came down to what can this fairly expensive device also do for me!!
I still like the Android tablet I recently got myself, but now that I have some experience with a few different options .. for value for money, the Windows based mechanical hard drive tablet option is close to ideal .... if you are a Windows user and not Mac or Linux!!(although I guess that Linux could easily be loaded onto the tablet).
I don't know of any Mac OS tablet devices available on the market.
Note tho!! Windows 8 is almost due to public release(apparently October), and Win7 on a tablet is not ideal .. it works but there are some compromises that need to be made for many programs(not just Windows itself).
Because my tablet's screen is capacitive touch, a stylus doesn't work on it(so I'm also looking for an ideal capacitive capable stylus).
I've trialled Win8 on the tablet and it seems to be a much better OS for a touchscreen device .. so if you decide to go with a Windows tablet, keep this in mind!
And from what I've read about the next incarnations of Win8 tablets, their processing power will be a couple of order of magnitudes above current similar devices.
** the 320G hard drive was nice to have, but it was a very slow high latency device that really made the tablet slow to load and do anything, when compared to most modern PCs. I relented and loaded a 250G SSD and the difference was startling .. should have done that a lot earlier.**
Do you have a budget limit .. either strictly imposed by any other half!!
) or philosophically restricted(as I do).
