Hard to say… there is currently no reliable indicator or measure of speculation. One idea was to graph trade volume vs transaction volume. This showed that there was a huge spike during the 2011 bubble, but there is no spike for the recent increase in price. You can see the graph here:

Hmmm, on second thought, this has the problem of double-spend, so perhaps it's not so simple. I suppose there really is no way around this problem of transfer-speed without using a trusted third-party.

It has always bothered me that it takes time to transfer Bitcoin. But then I realized that that's not necessarily true. You can actually transfer Bitcoin instantly by transferring your entire wallet. And just like real-world cash, you can then create many wallets, each with a certain denomination (such as 0.10, 0.05, 0.01, etc…) so that you can mix-and-match to send a specific amount of Bitcoins. Obviously, you will need a lot of "wallets", so we'll need new software to help manage its storage and facilitate this method of transferring Bitcoins. Thoughts?

By portable, do you mean via a USB drive, or do you mean via a mobile device? There are some nice Android clients out there:

I particularly like that these mobile apps allow you to transfer Bitcoins using QR codes.
