Good Point
Um, except for those of us that have laptops. The laptop just might not be at home when a family member wants to watch a movie. Then there is the decided performance gap between synced content and streamed content. Situations vary, but no doubt in the right setup streaming is a very viable solution. Flexibility is the key.
I do wonder if I streamed everything what would happen if I had to send my computer in for service. Not just the computer is down but now so is my atv at least as far as any of my own personal content goes ...
Good points.
Notebooks. Even if you kept your content on an external drive, then you'd still need another computer to serve it up via iTunes if you took your notebook out for a walk. If your notebook is the only machine in the household, then you're right - keeping the copy on the aTV seems a good way to go, as long as it contains whatever content that the non-notebook holding household member needs.
Streaming. While the joys of wireless are many, the lack of its reliability in my home took all the fun away. I wired the place up with 10 gigabit cable and have never been so happy. I don't get mysteriously disconnected and the transmission speeds don't fluctuate based on the rise and fall of the tide or the direction the wind blows. Instead, I get whatever is the weakest link in the chain, which is either whatever my ISP decides to give me or the aTV (as it sports a 100 megabit ethernet port, not 1 gigabit port like nearly, if not all, the rest of the current Macs, as well as the switch and router in my network). Sure, some people can't/won't install cable. For some percentage of them, wireless will work just fine, in which case streaming should not be an issue. For the others, it will be problematic, in which case, you're right, having the content stored locally (synched) on the aTV makes sense. I just hope that for this group, they have a backup of their content somewhere else.
Notebook Repair. You're right about what would happen if you had to send in your notebook for repair. So what would happen if your aTV needed to be sent in for repair? The point is that everyone needs a backup of their important files. As Macs running Leopard have TimeMachine built in, backing up files is easy. Of course, you can use other software too. As far as I know, there is no ability to backup content stored on the aTV, unless you use the synched machine as the backup. My strategy is to keep my content separate from the aTV and back up the content as well. I do that, because I run iTunes on a machine that doesn't leave the home. Given the low price of Mac minis, and the small compute/memory needs of iTunes, even an old mini would work just fine. Buy used from Apple and the current version clocks in at $499 -

Heck, you can even use an old Windows machine that might be collecting dust somewhere. This solution works for me. Given another feature set within the aTV (like enabling the USB port without hacking the machine), then maybe something else would be better - on the other hand, I'd still have to figure out how to backup the drive, so...
