Holdposition.....
Coincidentally, I have been investigating a similar dilema (likewise AOL) over the last day or so. Having only a laptop, I am looking to connect to broadband at home, but have the facility to 'dial up' when on the move.
I don't know if the office use element to your situation means that you would qualify for the same AOL domestic broadband rate as myself, £27.99 p.m., but I was advised that for £34p.m. I could have broadband with a 'dial up' facility; flat rate, NO call charges on both.
That said, I am seriously considering
Pipex as a broadband alternative, having heard good reports (although I'm sure someone will disagree!) and
in view of performance publicity. This equates to £23.44/flat rate, no call charges with additional 'dial up' available for £7.05/call charges at 'local' rate (both figures inc. VAT).
