For what it worths I have the same SDcard on the XO-1 with more than 1500 hours of swap use of a 256MB partition, with no problem so far.
On the XO-1.5 and its 1GB RAM a rarely see any swap use at all.

If anything I would rather see the extra cost towards a proper small SSD to replace SDcards, than extra RAM
