Most Honeycomb and above, Android OS nowadays supports reading external USB devices. USB host has been added. So you can transfer your Mini/Micro/SDCard files from your camera to an external USB Flash drive. I've been using my 7", Samsung Galaxy Tab 7+, and it works great.
On my travels. I really hate hauling a laptop, since you can't hold them with one hand, like a book. Plus hauling a power brick adds extra weight. I found that when I travel, there's nothing my Android Tablet cannot do. This is compared to my Windows 7 Laptop -up to a certain degree. If I ever need Windoze OS, I just remote control my home/work PC.
If you have an older Tablet or Reader, invest on an external card reader/storage. Cheapest one I found is around $110USD, for 250GB. Although I don't advice storing files to any hard drive that has a platter. This includes storing pics on your laptop, if the hard drive is not solid state (SSD).
