Hiya, started making a movie today. However, the lag seems to be lessening.. Dunno how that happened. When I first experencied the lag (and complained about it) I made sure there were no other apps running in the background, so I don't think that should be it.

Now, size of the file I'm editing does seem to be a factor. When I edit thet GettingStarted-file, the delays are like you said, 10ths of seconds. Acceptable indeed. When I edit the previously mentioned LaTeX file, the delay is a bit bigger but still not nearly as annoying as before. Weird. I know that Android can take a couple of days to start running smoothly sometimes, because of it learning what you tend to do and stash those apps in good positions. Maybe iOS does something similar? I don't know.

Anyway; delays like this are certainly acceptable. Thanks for listening to my whining ;-) If you find the time to smooth out the last bits of delay that'd be great, but I see how it is not a priority. Thanks!
Alright! I only have a crappy camera though, so it'll have to wait 'til tomorrow, when it's light out. Thanks for helping sorting it out!
I started with a 10.9KB LaTeX file. However it also happens when I edit the GettingStarted file. I'll see if I can make a movie, if that would help? I'm on iOS 4.2.1 by the way.
Well, I don't really see how you can think this is acceptable. It's really annoying to not see what you type appear immediately. Especially when using the on-screen keyboard, making a mistake while typing is somewhat common. However I won't see my mistake until a few keystrokes later. This annoys me to no end ;-)

PS: English is not my first language, and I'm not really fluent at it. Please don't take my comments the wrong way, I hope I don't sound too harsh.
