Just hope Apple decides to add a microSD slot. HD videos takes up ALOT of space. Same with the games now that the resolution has gotten higher. Think of memory like inflation. It might seem like alot now, but in 2-3 years it becomes a bare minimum.
A 20 min animated video at the original iPhone's resolution of 480x320 is at 70-90MB. At the 720p HD resolution (1280x720), it is about 750GB! We are talking about 10X more. So 80GB and 160GB for these HD videos is almost equal to 8GB and 16GB for those older 480x320 if you consider having the same exact videos. Of course, many videos will always stay at their native resolutions of VGA or QVGA like many of the older YouTube videos.
I remember even the iPod classic only peaked at 160GB. The reality is, not everybody will ever be satisfied with the amount of space. You might as well get them a terabyte. At least a memory slot gives you options without the waiting.
A 16GB microSD vs a 32GB microSD is only a difference of $30 at Amazon. We don't have to wait a year or whatever the next iPhone announcement will be. A non-expandable memory storage is never that great in the longer run. There is always ways to fill it up fast especially with HD videos, games, or highly converted songs. You are living off Apple's time and decisions to make it happen if you are yearning for more space. And I don't like that Apple's competitors decided to put only no memory slots in some of their devices. Think most WP7 phones (minus Samsung Focus), Nokia N9, HPalm phones, and the BlackBerry PlayBook. Apple makes great products, but they are not perfect. I don't want to see them influence others by not adding a memory slot.
A memory slot can be more cost efficient and eliminate all the waiting. More flexibility.
