In your situation, it doesn't sound like you need a laptop. You only mentioned you need to check e-mail, appointments, etc. I suggest you get a PDA. Many PDA'a come with wi-fi, so say you are at a StarBucks or at any wireless hotspot, you can get an internet connection. You might also want a smartphone. Many new smartphones are coming out like the Motorola Q. They have PDa functionality and many have wi-fi.
