Although the Casio E-125 comes with 32MB of RAM, you will most
likely need more storage in order to make full use of its
capabilities. For that purpose, the Casio E-125 offers excellent
expansion opportunities.
Located right at the top is a CompactFlash Type II slot. It
supports both Type I and Type II CompactFlash cards so you have
access to a whole range of upgrade options - from memory cards to
modems.

| CompactFlash memory cards are always a popular
choice. I bought the 64MB
ACE CompactFlash card and it worked great with the E-125.
Currently, the maximum size of CompactFlash memory cards is 256MB
although 512MB and 1GB memory cards are coming out soon. If you
need even more storage, you can always settle for an IBM
MicroDrive.
Next to the slot cover, there's a simple lock for the
CompactFlash slot which locks the CompactFlash card inside and
prevents it from dropping out. However, it will only work with
certain CompactFlash cards that have a special notch at one
corner. No need to worry though as most CompactFlash cards will
fit snugly into the slot and there's no risk of any card dropping
out of the slot.

| As such, there's little need for the slot lock. A card ejection
mechanism would have been a lot more useful. As it is, you have to
use stick-on tabs with certain CompactFlash cards that don't come
with an extraction groove. Otherwise, you will never be able to
remove your CompactFlash card after it is inserted!
Most cards will come with the extraction groove so you will be
able to remove them using a fingernail. Still, an ejection
mechanism would have removed the danger of a stuck card as well as
making it a lot easier to remove CompactFlash cards. Casio should
think about adding such a mechanism in its future Pocket PCs.

Casio should also rethink its cover design. It's flimsy and
troublesome to use. As you can see above, you open up the slot by
pulling out the cover. It's quite alright when you insert a card
but due to its awkward design, you will actually need to detach
the cover to remove a card from the slot. And because the cover is
attached to the Pocket PC by two flimsy hinges, there's always the
possibility of breaking the hinges or even losing the cover
itself!
HP's method of protecting the CompactFlash slot in the Jornada
Pocket PCs is definitely a much better way. Not only does it allow
for a slimmer design, it also allows for easier insertion and
extraction of the CompactFlash card.
