For $1,000, the premium Galaxy Note9 is a superb phone that showcases the best Samsung has to offer.

It's also the phone most of you won't need. That's because you can get many of the same features in Samsung's Galaxy S9 for a few hundred dollars less.

The Note 9 is the Android smartphone for those who want the latest and the greatest. There's a larger battery, with a 21 per cent boost over last year's Note8 model. The Note9 gets 128GB of storage, double what's in the S9 and Apple's iPhones. And of course, a large screen.

But there's not much "wow" beyond that. Smartphone innovation has slowed down in recent years. It's more noticeable with Samsung because the company spreads out those innovations between two major smartphones each year. One phone inevitably plays catch up with the other every six months.

So now we find that the Note9 is getting the zippy processor and cellular speeds the S9 phones first offered earlier this year. It's also getting the S9's dual-aperture camera for better low-light shots as well as its gimmicky, but super-fun, ability to take video with super-slow motion.

And the S9 starts at just $720 through T-Mobile, and about $800 through Verizon, AT&T and Sprint. A Plus version that's closer in size to the Note 9 costs $840 to $930.

True, the Note 9 offers a little more wowness. Its camera uses artificial intelligence to optimise colours and lighting for what you're trying to shoot, be it food, a sunset or flowers. Many low-light shots were even better than what the S9 produced, even though both share the second aperture designed to let in more light when needed. Of course, you're likely to see this feature in the S10 in about six months.

That brings us to one of the Note's remaining distinctive features, its stylus. It's useful for handwriting notes and signing documents on the screen. Now, it can control digital slideshows and music playback, too. The new stylus gets Bluetooth to double as a remote control. Selfies won't look as awkward when you don't have to reach for the on-screen button; just press the pen to snap the shutter. Unfortunately, there isn't a lot the remote feature can do yet. It's a promising feature - but could remain mostly a promise if app developers don't take advantage of it.

Many past Samsung features failed to gain traction because app developers couldn't be bothered to make the tweaks needed. For instance, Air View was supposed to offer pop-up previews just by pointing to an e-mail and calendar entry, but it mostly worked only with Samsung's homegrown apps.

More recently, there's Bixby, Samsung's own digital assistant. While Samsung has worked directly with some services, including Uber and Spotify, on integrations, developers have largely prioritised Amazon's Alexa and the Google Assistant. It comes down to a chicken-or-egg problem: people need to see compelling capabilities to use a feature; developers need to see a strong base of users to spend the time developing compelling capabilities.

The stylus remains the Note's signature feature, with or without extensive remote capabilities. No doubt the new edition will appeal to die-hard Samsung fans, hard-core gamers and on-the-go executives who are on their phones constantly and need the battery and storage boost. Though the Note9 uses the same processor as the S9, it has a new cooling system designed to let you use those faster speeds longer.

But if you're not someone who needs all that power, you ought to take a second look at the cheaper, six-month-old S9.
