More iApps probably.
In relation to the thread on the Danger hiptop softphone/PDA, Apple should license a version of that and add 3 key features - 1) AirPort (or 2.4GHz wireless) 2) FireWire and 3) SIP protocol support.
SIP (Session Initiation Protocol) is really important. That and H.323 support are is the key for enabling voice applications on desktops and PDAs. As companies move to Voice-over-IP it enables a whole bunch of options because much of it can be done in software. For example, there is a SIP client for iPaq PDAs that turns it into a wireless phone over 802.11, that you can use in a company environment over a wireless LAN, it becomes an extension of your desktop phone.
We've tested this sort of thing, 2 of our engineers brought Cisco IP phones home and they called each other directly over IP, through broadband connections. It's an end-run around phone companies and long distance charges

It would be great to have an iPhone (
www.iphone.org) that could be an extension of your home phone at home, and logs in as your office phone at work
Apple should look at incorporating a lot of VoIP technologies into OS X - there are a lot of telephony code stacks for Linux and System V Unix that could be ported. So far, only one company, Dialpad, has a VoIP client for OS X.
A software iPhone on every OS X desktop would be a big value add when selling to Fortune 500; they could beef up H.323 support so that OS X users could videoconference seamlessly with Windows and *nix users; they could license some technology and even replace that horrible FaxSTF application with a Personal Fax-over-IP solution.
For networks and LAN administrators, they could license and market their own VoIP softswitch and voicemail system (call it Phone Studio Pro
- or at least make sure iPhone hardware/software is interoperable with industry-standard VoIP gear like Cisco, VocalData etc.
Other than that, I'd love to see Apple buy Ableton Live and sell it as iMusic (
www.ableton.com) - the thing just looks like it was made for OS X (and it is!) ---
and there hasn't been a decent basic Web-design app since Claris Home Page. I suggest the WebObjects team could come out with iWeb, a graphical IDE with plenty of templates and drag-and-drop code objects to let even beginners do sophisticated design as simple as Lego - WYSIWYG layout, easy forms/buttons/scripting, rollovers, graphics optimization, imagemaps, tables, and full support for CSS/layers etc. There could be "Upload to iDisk..." and "Publish to /Public" commands for one-step internet/intranet publishing. In a similar way to Freeway it might allow the import of any graphic type as "layers" and then it would use the Quartz engine to flatten them and export an optimized image / CSS layers.
