As far as softmodems or controllerless modems go Agere make some of the best
so although just like yourself a software modem or controllerless modem
isn't my modem of choice, I'd stick with it. If it aint broke don't bother
trying to fix it. I think with a laptop pc softmodems are excusable because
they result in reduced size and weight. The next step up in my book would be
to put any modem related savings towards a wireless router (assuming your
laptop is wi-fi capable) and an adsl/broadband connection. Once you've gone
broadband (assuming its available in your locality), you wont want to go
back to dialup.
