With iPhone knock off PCM Keyboard v0.12, I don't miss my Mogul.
Much.
Well, OK, I still miss the physical keyboard a little. Also, the better LCD in the Mogul, much brighter and better color/contrast. Although it's not viewable in direct sunlight like the Touch's transreflective screen. And yeah, the Touch's camera really sucks compared to the Mogul's.
And they both have leaky RAM, the Touch having twice as much RAM, means it can leak longer.
I'm using transcriber a lot more, and PCM Keyboard other times. The Touch has a much better physical build quality and styling, it's just so solid.
