It would be great if it had a color screen, and airport connectivity. Then I couls use it as a PDA/remote for my laptop. Connect my laptop to a stereo and I've got one killer jukebox!
The grace of the Newton? The Newton was graceful? I saw one in the office the other day (in a heap of old machines no one uses anymore) and it looked..... like a brick.
Maybe if the Apple PDA was a real tight version of a Sony Ericsson P800.
Or visualize a P900 in an iPod industrial design.
I really dig the P800 i have, its practically a computer, but wish for some more mac<>phone connectivity options from the phone side.
Maybe wi-fi, better contact handling, and the ability to use my powerbook keyboard to enter data in the pda directly. Oh would be nice to be able to share iPod accessories.
Yea i'd buy one then in an instant.
--edit--
yea then i'd have to give someone my newton
My little "dream machine" would be an Apple branded combination of a Treo 650, Sony CLIE PEG UX50 and iPod mini:
Mobile phone
Camera, that could be rotated (like the one on the CLIE), so it could be used for iChat AV videoconferencing (or just taking pictures)
iPod dock connector, for connection to firewire or USB2.0 ports
Built in hard drive - minimum of 5 GB free capacity
802.11g and BT
A decent built in thumbpad keyboard (and ideally connectable to an Apple BT mouse/keyboard)
Connectable to an external projector - via s-video and/or 802.11g (with a mode so that buttons on the thumbpad keyboard could be used to navigate slides)
Syncs with iTunes, Address book and iCal
Decent Applications (!):
Quicktime
Preview (for PDF and image viewing)
Mail (esp. one that can automatically syncs with the Mail in OS X)
iTunes (esp. capable of playing audiobooks from Audible.com)
Keynote
Safari
iCal
Address book (although I think the Address Book in OS X is in need of some updating)
TextEdit (with capability of opening Word documents)
