The ability to store activities to card was something that interested me (I'm thinking 1000km, PBP etc, rides here - my 305 overwrites old data after around 600km). But it's a bit of a serious limitation if I can't then offload that data afterwards!
Even the 705 has 500mb of built-in storage. Power data makes the files about 5x larger and I still have data files back to August on it and it's only 2/3 full. The data shows up as files on an external drive, and you can copy them wherever for backup and/or to make more room. I have a 2gb micro sd card in it and have all of my 2010 data on it.
Note that it won't ever overwrite old data, if you fill it up it just won't write new data.
