While I agree that the typical user isn't particularly effect by that (most people don't keep anything on their phone except a few apps). But fixed memory is a definitely a step in the wrong direction, and a completely unnecessary one too. There is no good reason why you can't have an sd card slot except that it would cost the OEM more money per phone, and they'd have less opportunity to price gouge you for higher capacity versions, following the Apple model. Going from a 32GB iPad from a 16GB one costs $100, with another $100 to go to 64GB. A 32GB microsd card goes for just over $20, and a 64GB for about $100.
No offense, but alot of this talk how the non-removeable storage card "really isn't as bad as you'd think" sounds just like the Apple Apologists rhetoric. That's up there with "What death grip? Nobody holds the phone while making calls anymore."
