Good news. I found this site that has some good information about what to expect and plan for when travelling with electrical appliances and gadgets. I've discovered that the power supply for my laptop indicates that it can connect to AC 100 - 240v ~1.5A, 50-60Hz. So I won't need an adaptor for my laptop after all.
Aaaaaand I have to give Dell some credit since the mini-brick adaptor for my Axim X50v is also rated for AC 100 - 240v. Just like my 600m brick.
Question: what's the availability on AA batteries in the Philippines? I am going to bring along our Canon A60 digicam - Gail's old camera - and it runs on 4 AAs. We use energizer Nimh rechargeables and I've just confirmed that it is only rated for AC 120v.
More digging required I guess..
The plan right now is to bring my laptop - primarily to be able to download photos from the digicam, secondarily to be able to communicate with the home-team.
My friend Michael is currently in Patagonia, in the Southern-most town in the world. I know this because he MSN'd me from there. Yeah, they've got broadband there too. So I'm hoping that I'll be able to find an internet cafe in the Philippines that has broadband access.
