Despite the fact that we never mastered the keyboard, we were still able to frequently type emails and text messages fast enough to get ahead of the i607's ability to process individual characters, leading to a frustrating lag between what you're typing and what you see.
While lags are expected (economists speak of a J-curve effect that accounts for the process of adjustment to the new prices in both countries), a two or three year lag in an era of instant communications, cyberspace transactions, transnational production, and airtight supply chains is simply not credible.
