I only have an analog line during holidays, so it's a little bit slow, but enough for mails and blog. Too slow for bloglines :-(
I'm charged 8 cent per minute for online access (by t-online, I have a call by call access) and local telefon call costs (don't knwo how much it is exatcly). There is a central access number in France for analog/ISDN dial-in: 08 6050 1000
