typonautobcorrection
By far, the most common typo I make on the iPad virtual keyboard is typing an “n” or a “b” instead of a space. So, I end up with a large number of combined words like “combinednwords” or “largebnumber.”
One thing I noticed is a bit different between iPhone OS 3.1 and 3.2 is that 3.2 will auto-correct “thisthing” to “this thing.” Steve Jobs even had an “oops” moment in his iPad introduction which very slyly showcased this. But now, with these typos I mentioned above, it seems like a no-brainer to extend that auto-correction feature to include properly-formed words which are concatenated with a random letter.
