The Perfect Gadget

I have been thinking about getting a PDA. Something with wireless. I also want a full sized keyboard. There are some fantastic examples of this: the Tungsten C, T3; the Dell Axim. But I was thinking about getting a laptop too, one of those tiny ones. A Sharp Mebius, or Dell latitude LS, or Fujitsu Lifebook P might do the trick. Something like that anyway. The quandary is, I want to be able to use it easily, especially type, and I want wireless. Extra stuff that would be nice is storage (laptops have 10 gigs plus hard drive space), portability (PDAs), ability to run java (palm PDAs and laptops), MP3.

Anyone with experience with anything similar to these products should feel free to comment. Please.
