Ask HN: Gadget Question (A device that has email, google reader, twitter)

Is there any gadget out there that has the following capabilities and is under $20/mo. for a 3G data plan?

- 3G Connection - Google Reader - Twitter - eMail

Peek comes close, but no cigar. iPhone has 'em all, but with a $100+/mo. pricetag; same with most noteworthy pda's. No purchase-worthy available tablets, right now.

Thanks
