Yeah I'm not entirely convinced that they would update just the few changed bits of the file. I guess they might, its not even that hard if you just have all the data what to do and where. I do agree dropbox PC client is very fast on big files so they must do something smart. But do remember the full blown client is in a constant pipe connection to the remote servers to get all data/updates/notifications immediately. I on the other hand have to use a REST api so polling for changes.

You can think of it this way: you have quite ok working sync while as far as I know the DropBox companys own iPhone, BlackBerry etc. mobile clients dont have any sync at all. I think the other operating systems might be the limiting factor to a point, so yey for maemo

You can't compare just on speed because one of the things that are really slow on the n900 (and similar devices) is writing to the non-onboard nand (where the rootfs is located) compared to the a regular HD.
I don't know how dropn900 handles it, butit could probably save some speed by splitting up the downloading thread from the thread that saves it to disk. (instead of having a read => write loop).

@jonnenau: Just wanted to give a shout out and say thank you very much for everything you put into making this app work great. Saved me quite a few times in the past 2 weeks.

Thanks, glad you like it. I am really doing this for you people as I don't use my own app at all

its kind of funny how much hours I put to it without using it beyond testing for releases.

I actually do have separate threads for writing files to disk and getting them from the network

So when the network fetch is done to memory I start writing that to disk in another thread and start the next network thread at the same time. If you are into code here: TransferWorker and DataWorker. Let me know if you have ideas at making the code better, I'm always open for that.
