My TX has a SD memory card slot. Everything I journal goes there. It gets swapped into the computer in the next sync. Or if I want it to go to the web fast, I just pull my data off the card via an SD slot on the side. Then it goes straight to the web!
Other options are uplink via bluetooth or the wireless web that the TX comes with. I have written a post sitting at a sandwich shop. So There are many options!
