Hello, My dad wants a laptop. He travels a lot, overseas to China. Laptop Requirements: - Travel-size friendly. - Under $500. - Fast for online stock trading. - Able to connect easily by wireless. I've priced-checked some laptops and honestly, I'd like to get him a mac so he doesn't have to deal with any viruses. Any opinion on the 12" inch latest rev of the powerbook? He trades stocks online so I'm slightly worried about compatibility. He wants the laptop for getting online fast and trading stocks. He doesn't need photoshop or anything else like that. Also, does the 12" powerbook have problems with weak airport? I know my 15" Powerbook sometimes can't find a wireless signal and my sister's macbook or my cousin's dell can. Thanks!
