Sony is quick to respond to questions on Amazon, but I don't know if this is a plus to their business.I've never seen so many NO on an Amazon product page:

No, there's no dictionary, No, this does not connect to a Bluetooth keyboard. No, it doesn't sync with dropbox directly. No, this only supports Windows/Mac systems. No, it doesn't have a browser. No, there's currently no plan to add one. It becomes hilarious after a while.
