I think this is absolutely the key..
If these devices take off for LG and Samsung, I hope to hell they'll follow them up with more devices. Because Nokia has utterly and totally lost the plot when it comes to making smartphones.
Before I get flamed for that last sentence, let me explain my rationale for saying that. Nokia seems to be either holding steady or reducing the amount of RAM in each phone they release. 20MB of RAM (or less!) to run your applications in a modern smartphone is embarrassing. There's no excuse for this.
It's even worse when you consider that small amount of RAM is being tasked to run a browser that displays webpages in a manner which has no business existing on a phone. Why the hell did Nokia think it would be a good idea to force people to scroll in 4 directions and zoom in/out to look at a webpage on a phone? The browser is good for one thing, and one thing only, and that is impressing people. Once you sit down and actually depend on the thing and have to use the thing, you'll find yourself heading over to mini.opera.com faster than you can blink.
The email application is a joke. It was bad in 2003. It's worse today. You still can't save unknown attachments without using 3rd party software. Note to Nokia: I may want to save these attachments to my memory card and then copy them over to my PC using the whole 'USB Mass Storage' thing you've so kindly provided in your phones. Look into this.
Someone at Nokia, please, please, please look at the contacts app in Windows Mobile and clone it. You did a sort of good job cloning the Today screen. Don't stop at one idea.
So my hope is that Motorola (it is Moto I think, not Samsung) and LG look at the existing S60 devices out there, notice what blows on them, beef up the RAM, license Opera, bury the Nokia Web Browser Deep-In-A-Subfolder-That-Mortals-Dare-Not-Enter, and make a great smartphone. And leave the Multimedia Device bits and pieces to Nokia.
