I'm wireless b/g at home. My printers (HP) are networked for shared printing.

I would like to have a unit that is capable of the following and I want to spend the least amount of money. Any extra/added features other than what I want it to do are of no concern to me.

1) Connect to my wireless Internet connection.
2) Recieve Email attachments (tiff or pdf format)
3) Print the attachment to my networked printer.
4) Be handheld.
That's it.

Any ideas would really be of assistance.

Thanks.
