I'd definitely buy one backcover, not sure yet if I'd prefer a flat one or an extended one. I'd probably order both to be able to switch depending on the situation (extended only for trips or days when heavy usage of the N900 is expected), unless an extendable backcover (such as that suggested in the previous pages) is built.

Later, when they will be available, I could purchase additional parts to have a full body replacement for my beloved N900.

Keep up the great work Estel.

By the way, when the parts will be available for purchase, you'll probably have an additional order for a "USB port soldering" manipulation Estel, as I read somewhere that you can do it for European users. If you can also fix USB ports that are already broken, then you'll receive two N900 units, and I'll purchase another backcover.
