I purchased Texttastic the other day because my MacBook Air is in for service. Great text editor and if paired with a bluetooth keyboard you almost forget you're not on a laptop.
I love Textastic! It's custom kb makes programming super easy. I love code completion. The cursor control thing is brilliant.
Not sure if you've looked at TextExpander but I find it to be a nice compliment to Textastic. I created some Django shortcuts that seem to work nicely. %%ifeq turns into {% ifequal %}{% endifequal %}
