I use the 2Gb cards.
The 'only' probelm I've had once - the GPS did not 'see' the card at some time during the day - previously ok. I took the card out and put it back in .. gps now sees the card. !@#$$# ... Later when downloading the tracks .. some were mssing .. took the card out of the GPS and put it in a card read - all tracks now avalible.
Whatever you do - take more than one card with the maps on it .. T4A is less than 100Mb, take Island Oafs Morrotopo too .. still less than 100Mb IIRC ..
------------
Daily logs are fairly small .. say 300kb each day (set on most) ... or less depending on how much you do in a day.
