Two Logical Reason Why Siri Isn't Supported In Older Devices, Can't Handle It [apple, ios, iphone]

There had been a lot of talk and complaining about Siri been limited to the iPhone 4S when hacks had proven it can run on older devices.

I think there are two logical reason and while one is widely known the other one have been overlooked.

Pushing iPhone 4S Sales

This is the reason widely know. The iPhone 4S has many new internals that makes it a solid device but it carry the same look as an iPhone 4. 

Siri been so cool is a must saw feature and by been exclusive to the 4S it help it sell better. That's pretty much covers reason number one.

Siri Is Not Ready For 250 Million Devices

We like Siri, a lot of people do and we also know that Siri is on Beta so it has some testing and hiccups to overcome. 

Last week Siri suffered its first major outage and while many complained other saw it as an indication of its success and adoption and I agree with the later.

If the use of Siri by iPhone 4S users alone was enough to cause a widespread hours long outage what will tens of millions more devices do?

Evidently Apple wants to scale Siri from the iPhone 4S forward. That will give them time to improve it while at the same time avoiding angering its user by limiting Siri's outages. If Apple made Siri available to older devices the load on the service will definitely bring it down and my threaten its adoption.

So why Apple din't plan for it?

Siri carrys a significant investment and while Apple has tons of cash the company hates wasting it (not like HP Palm). So Apple decided not to invest the upfront cost needed to support older devices in case the service was a flop. After all the iPhone 4 major feature Facetime isn't a super success.

So its simple Siri may run on older devices but the backend can't handle the load.
