Hi,
In order for bitcoin to ever (truly) be able buy a coffee, sandwich, magazine, groceries,...
transaction speeds of bitcoin payments at the counter must be instant.
This needs to happen or bitcoin will never be wildly used and accepted.
Apple will likely be coming up with "apple dollars" sometime soon, so people
can pay for their Starbucks coffee, and offcousre it will be arranged in such a way
that you can leave with your coffee (or whatever) instantly...
So in order for bitcoin to truly survive, faster transactions a needed... or a workaround
method like a escrow is needed. (

However such an escrow for bitcion would also need to work on an iPhone.. so it can be widely adapted
Witch is tricky as apple would never allow such an "escrow app" in its store.
So would this still be possible to work on an iPhone, via html5 or something ( so apple an't block it ) ?
If not, I fear "apple dollares" or something else might overpower bitcoins at one point in the future...
( yes I am sure you can buy groceries / coffee with bitcoins at lots of places right now,
but companies do this mostly for publicity,
for it to ever be usable in the real world by everybody there need to be some changes!! )
