True, it doesn't have huge internal AND external flash storage. Nice thing about the Droid is that you can add up to 32GB of microSD storage to it and use it to run apps. (You can either go about the plain vanilla method of moving qualified apps to the SD card, or use the rooted APPS2SD method that CyanogenMod supports.) This isn't like the N900 where you're stuck with an incredibly teeeeeeny partition for your home and apps. Additionally, there's a huge push to get data into the cloud--so you don't have to have a lot of storage on the device for your calendar, email, music, video, etc., if you want to be able to sync or use your data across lots of devices. (Personally, I prefer to keep most of my data local, but some things I prefer in the cloud like my email, contacts and calendar... those just magically appear on my Droid *AND* Galaxy Tab.)

Because it's the nature of Android from the beginning, it is able to do true multitasking for any apps that are enabled to multitask in the background... and any apps that an author wrote to be able to freeze their state when they're thrown into the background will do that instead so that you don't eat up battery life (as opposed to constantly running idle applications in the background like in Maemo). You'll note that this DOES provide you with the best of both worlds--you can get true multitasking from apps that should be able to do so in the background while getting FAR better battery life. What are you running into that isn't multitasking for you?

I'm sure most of the people who puffer on about how great a phone the N900 is have never used anything else, but that's just natural. I blame Nokia, mainly, for doing such a half-arse job of something that even the Skype application does a better job of doing. :P
