One common exception is mobile GIS. If the PDA does not support SDHC you
are stick to 4 GB card + your internal ROM at max. It's easy to run out
SDHC would let you have 32GB (but now only 16GB is widely available at a
resonable price). Yet you have to be lucky that your PDA supports SDHC,
cause it's a fairly new thing and you don't change PDAs that frequently.
Just 0,01 PLN worth rambling.
