I recently acquired a new pocket pc with bluetooth (HP1945). I have several questions.

1) I would like to know if I must purchase an adapter/dongle for bluetooth to connect to internet on my pc.
2) It's my understanding that if I do connect, I must stay within the same room as the adapter to use my pocket pc. Please correct me if I'm wrong.
3) If this is so, I may be better off getting a wi-fi setup and purchasing a SD wi-fi card.
