Also, this is just me, but I prefer my sound to come from the thing I'm looking at. I honestly don't even like the idea that everyone is so fond of about moving the speakers to the top of the base instead of surrounding the screen.
I think most of us don't particularly want to move the speakers, but we do want a larger screen without making the device larger. Also a screen with less bezel around it would look nicer and more modern.
My suggestion was to make the speakers point outwards somehow, so we don't have to take away area from the top of the base (we can use all the area we can get for the planned extra keyboard keys/controls), and so the built-in speakers are more useful in lid-closed situations.
Of course you're going to get the best audio quality with speakers that are pointed at your ears. That's why you put headphones around your ears and not around your feet. But a handheld device is about making compromises: you can't have a 21" screen, you can't have a full-size keyboard, and you can't have real speakers.
When do you use built-in speakers? In environments with lots of background noise, you'll use headphones or external speakers anyway. When you need excellent sound quality, you'll also not use the built-in speakers. So when are built-in speakers good enough?
- games with some sound effects that are not essential
- listening to a radio show or youtube video or something like that
- alarms, incoming mail/sms/whatever notifications
- making a phone call
- listening to music if you don't care much about quality
- you didn't bring headphones so it'll have to do
The advantage of outside pointing speakers is that they aren't muffled when you close the lid. Closing the lid means more battery life (no screen), pocketability, looking better if you hold it like a phone, and being mechanically stronger in case of accidental drops etc.
The advantage of inside speakers is that they can be aimed better in the direction of the user -- assuming it's a single user who holds the device like a handheld (which is of course the normal use case).
