Danger Hiptop 2 / Sidekick II

OK, so my SKII broke this past Thursday.

I know SKII is still for sale on T-Mobile's website...

They're trying to get me to upgrade to their MDA phone...

I haven't yet exhausted all of my options for getting a new SKII...

I'm just wondering what's best - SKII vs. SKIII vs. MDA...

I don't think I like MDA...

I could care less about Bluetooth...

I'm deaf - I don't use voice. I have a data-only plan from T-Mobile for my SKII...

Anyway, can't get a SKII in the store! They told me I could get it in a store - went to a store - they said they were all out - an hour's drive for nothing! Gee.

Oh, and I'm a Mac user, so I could care less about PC enabled phones, too.

I'm also open to a good SKII alternative that's good for deaf people...

I love my SKII for its calendar, to-do list, address book, web browser, and IM. Those are the biggest. Oh, and the data-only plan for only $29.95 a month! Anything like that out there? Or is there no substitute for the SKII?
