Powerbook Friendly

I’m the proud owner of an Apple iBook notebook. I’m quite happy with it, but at the same time I’m tempted to change it for one of the new breed of Powerbooks, since they have reduced their price in a very interesting way. This can sound a little dumb, but I need more power for my applications (Reason, Photoshop, etc.) and I don’t want to spend US$ 2500 in a G5 dual processor computer (It could be really nice, but money is always an issue). My main problem? I live in a Spanish speaking country and my iBook has an English keyboard layout. I’m going to offer it through eBay to see what happens. The worst case scenario would be to have two laptops, and using only one… I’m confident that someone will help me out.
