What is mLinux?
If you refer to the "distribution" of Linux put together by Lisa
(Hamburg) then mLinux is more or less an ordinary handhelds.org
StrongARM Linux.

The more interesting option is BT Compact Flash cards which will be
available soon. The problem is just that the interface is not specified
in the BT specification. So every hardware manufacturer will do this on
his own. Thus it will be very hard to get the correct interface
specifications :(

The IBM stack has the additional disadvantage that you do not get it's
source! So you cannot recompile/port it for StrongARM...

Get a CF card from a verndor/manufacturer that will share the specs with
you. That's what I am currently trying.
