I'm not sure why people keep comparing these programs .
Things just came out of beta yesterday, still has lots of bugs .
They just released an update to their iPhone app , it crashes every time you try to manipulate tags on the iPhone.
Agree with all the comments made below ..IMO lots of " things " no pun intended for them to fix/ implement before it's a mature product .

the " today" list and the tagging always look so promising at home ..but as soon as I'd actually try them in battle AKA " work " they didn't work for me .
