It's clear you need a keyboard and IMO you should wait until SIP works on Sailfish (Jolla) exactly the way it does on the N900.

It might some day but as much as I like Jolla, as ex-Nokians they appear to be still shellshocked by the rapid decline of Maemo devision and the whole of Nokia soon after in a way that they assume the N900's basic integrated features are NOT what the market needs first.

I have both Jolla and N900 and if the N900 breaks down I buy another N900.
If the Jolla breaks down I'll hold my next move and wait for Jolla to resemble N900 II closer.
