Babak Nivi via Emergic.org, The Next Killer App Will Be Developed on Apples OS X:
Theres good reason to suspect that the nets next killer app will be developed on Apples OS X operating system. Among many computer developers, there is a strong movement from Linux to OS X.
Why? First, OS X combines a open-source Unix core with the worlds best GUI and best-of-breed applications like iTunes and iPhoto. Rumors also indicate that Apple is going to be integrating Linux with OS X in their 10.4 revision.
To be taken with the necessary amount of salt. The Linux integration, it would make sense as FreeBSD does it already (in a very interesting way, it's not an emulation, it's a direct binary compatibility).
The Voice and video over IP are definitely plausible:
If VoIP and Video-oIP are the next killer apps on the net, Apple already includes truly turnkey VoIP and Video-oIP in OS 10.3. They will sell you the hardware (an iSight plug-and-play auto-focus video camera) that integrates Video-oIP directly into AOL Instant Messangers namespace. Watch for them to extend it to the PC platform like they did with the iPod.
This one, I would love to have figures to back it up:
Among many computer developers, there is a strong movement from Linux to OS X.
Personally, I'm hearing from several Java developers that their PowerBook with Mac OS X is the best workstation they've ever seen (which makes me happy, since I made them switch ;-). But they switched from Windows, not Linux. If Mac OS X 10.4 brings them Linux à la FreeBSD, they'll love it I think.
You're not forced to believe me and I know this depends on what you want to achieve, but for me, Mac OS X is hands-down the best computing platform on the market today for many, many applications.
