Help! Which Way Should I Go?

Here’s my dilemma: I own a nearly 3-year-old Macbook. I also own an iPhone (contract expires this June), but I find it hard to read and communicate on, though I do my best. (Bad eyes?) I want to have something (not just a Kindle) that is lighter and smaller (with more than wifi). The Macbook is actually fine, though it doesn’t have much memory and the fan races when I try to watch any videos.

Soooo, I am pondering these choices. I ‘d love to have you all weigh in on this.

Option One: Buy a new Macbook Air and keep the phone. Use the Air for most everything (I’ll buy a 3G card)

Option Two: Buy an iPad and keep using the Macbook. Take the data plan off the iPhone (don’t want two data plans)

Option Three: Buy a Xoom and keep using the Macbook. Take the data plan off the iPhone

I’m thinking I may also need a Kindle, but maybe not if I have the iPad or Xoom.

What’s the word?
