How about an Apple POS system? (Point of Sale)
They have the technology and the niche is currently owned by Symbol (a Motorola division).
That *could* explain the various screen sizes.
Anyone thought of an Apple IP phone? To compete with Cisco? Again, they have the technology and could pull it off...
Woah! Hold your horses there buddy.
1. POS system. Are we talking static system in stores or portable? Its not just Symbol that offers them and not all are PPC devices, most or pure WinCE or worse. Also, getting into such a market means replacing the wireless link, the database in use, servers, links to other corporations and their DB for the orders or shipments received. More than you thought of. However, Apple does use their iMacs for their stores for static point of sale terminals.
2. Go up against CISCO?!! You realize that the whole PBX, IPSEC is CISCO's bread and butter right? This is industry standard technologies. Apple in the past is known for mixing standard tech with their own proprietary tech =/ never good for business.
Avaya also participates heavy in this industry. And its more than just the "iphone" that users or corporate business' wish to use their smartphones to have 1 line with - personal out of WLAN range, corporate line when in range.
To get into this corporate business Apple is up against:
Microsoft (Exchange is going pure Unified Communications)
IBM (again UC via Lotus Notes/Domino and sub applications)
Avaya (PBX phones, terminals)
CISCO (same as Avaya - larger margins larger customer base)
Polygon (VoIP ... Video/Voice over IP with HD definition).
etc etc.
I like your thinking ... and Apple SHOULD for the love of god start catering to the corporate world too. I still feel Jobs is scorned due to that Lemons commecial long ago.
