There are still special purpose devices for this, eg.

I'm doing a big trip later in the year and I'm leaning towards a small laptop, but a special purpose device like the Epson probably suits some people better.
A 32GB card is a wonderful thing, but I'm not sure I want to trust several weeks of memories to a single device, especially one with a crappy Microsoft filesystem on it
I also do a lot of HDRs and panoramas, and it is suprising how much storage gets chewed up with multiple exposures.
Cheers,
Rick.
