Would it be possible to add slot for memory bank? (Connected to n900 motherboard properly). It would be cool to have 1.2GB ram in N900 working (256MB internal + 1024MB in-cover) I hope n900 to be electrically compatible with notebook memory banks (or else it would need special parts which would be accessible only in large quantities)
Other insane idea is to include miniature usb hub on the left to split between full sized usb port and builtin usb to ethernet adapter.
