NEW YORK ( RealMoney) -- It's not surprising that Amazon ( AMZN) showed interest in Research In Motion ( RIMM) over the summer.

Amazon has never been a big supporter of Google's ( GOOG) Android OS for its Kindle. And Google's never been keen on promoting Amazon as part of the Android ecosystem.

It seems that both companies know this is just a matter of time before each leaves the other.

Why would Amazon want RIM? RIM's QNX operating system is a very powerful alternative OS for a determined third party like Amazon, who doesn't want to rely on Android or Microsoft's ( MSFT) OS. If you're determined to do your own thing with your own software platform, then QNX is attractive alternative. I'm sure Amazon must have also looked at Palm's OS from HP ( HPQ).

QNX was built primarily for cars and larger-scale consoles. RIM has done the work of skinnying it down for tablets, which would be Amazon's initial interest for it.

As disappointing as RIM's PlayBook's results have been this year, the tablet still got high marks for a zippy browser. That was one of the big criticisms of the Kindle Fire when it came out.

The real question: How many Kindle Fire version 2.0's could Amazon sell with an upgrade of the PlayBook? And would Amazon want to get into phones? There have already been rumors of its interest in going in this direction. It's obvious that RIM isn't ready yet and won't be with the first QNX phones, which aren't due until late 2012. If Amazon was to get RIM now it would be getting the QNX operating system with a lot of heavy lifting already done.

Now, I'm sure it's true that the RIM co-founders -- who are delusional -- dismissed the idea of Amazon buying them earlier this year. In their skewed view of the world, they've hit an air pocket. This is just a blip before they restore themselves to their rightful place at the top of the mobile heap. So why would you even consider selling yourself for $30 when, just a few years ago, analysts like RBC's Mike Abramsky had a $250 target on the stock?

I think the RIM co-founders will be even less likely to sell now with the stock around $13 to $14.

That's probably why we're starting to hear these rumors now (from Amazon's bankers). Amazon is trying to force some external pressure on the obstinate co-CEOs. They're trying to rile up the RIM shareholders to accept a deal.

Would Amazon, a consumer company, want to take over what is essentially an enterprise company? Maybe. They'd likely keep RIM as a standalone company anyway, so that it could continue to operate in Canada and pass Canadian regulatory approval. The new RIM would continue on with the old RIM. It just would get new Amazon management and Amazon marketing, both of which would be greatly welcomed.
