I’ve finally downloaded Skype and signed myself up for their unlimited US + Canada call plan so that I can call my parents on their cell phones from my computer. It works pretty well, all things told, although my laptop’s built-in microphone leaves some things wanting and I’ll probably get an external mic once I get there. Once I work out the time difference and my schedules, I’ll actually be able to call landlines and cell phones in the US and Canada (for less than $3 a month!). It’s much smarter than trying to get an international phone plan when I’m in the UK.
For those interested, my Skype name is “cgcunard” (the same as my Berkeley e-mail).
