It doesnt have as much battery life, but that doesnt matter to some people. I've never been in a situation where I have to be away from an outlet for more than a couple hours, and I'm almost never in my dorm. A mac might be reliable, but it outlasts it's hardware capabilities and, as far as I know, can't be upgraded (probably the reason I never would consider one). My gf is already tired of her 2 year old mac pro because its gotten to the point where it cant handle newer things, it even takes a good while to load gimp (considering the size of the program). And she also is a computer science person and regularly cleans the computer etc. That toshiba will be able to handle the new macromedia flash and photoshops and such fine, and a toshiba is a very reliable computer that'll feel nice n strong and durable in your hands unlike the $300 hp sitting next to it in best buy.
As to the power thing, I've never come across a laptop that can take either (though I've never checked on macs which might be a selling point here). All one's I've had have said they need a 110 input on the power adapter. Not only that, the philippines might have a different shape plug (i have no idea here). I've been to countries that do have different plug shapes though.
