I have an iGo Stowaway bt keyboard, while I do not used it much except when I don't have a laptop/desktop around. It also works very well with my symbian phone which I use it more for. BTW, I use SSH with Winscp & Putty on my desktop/laptop so I can cut and paste from documents...even this forum...which is easier then typing IMHO even on the N810 with or without the BT keyboard.
