I'm new to Android so can someone help me out with why an SD Card slot to the average person is so important?
(serious question)
Actually, there are various reasons why an SD Card slot may or may not be more or less important to different people.
As someone else pointed out early on, that person makes a 2-hour commute by train to work and back every day. The extra space for them is great for movies rather than having to put up with higher battery usage or lack of connection quality when quickly passing different connection towers. Others may use it for testing or backup purposes. Many different people have many different reasons. Some of those reasons may be more common to a larger mass of users while other reasons may only pertain to a smaller group of individuals.
For me, I personally use my phone in many different ways and use many different types of apps on my phone. I use my phone is so many different ways where I need many different types of apps that I run into problems with my current internal storage limit of 16GB even though I still have plenty of room on my external SD Card.
Reasons for this is because not all apps are able to be installed to the SD Card. Some, just by choice of the app's creator(s). Some, because they need to run from internal storage for performance, security, and/or other various reasons. A lot of included bloatware apps also tend to run on internal storage only. And, for those apps that do install to the SD Card, they still partially use internal storage for other various reasons such as operating-system settings and configurations etc.
There are also some larger apps that are usually standard installs for a lot of people that can be huge internal storage hogs. Adobe Flash and Acrobat are a couple of examples. The Facebook app for Android also currently will still only take up internal storage and it takes up a ton of it. When available, I have had to look for alternatives to certain apps that can install some of their components to an external SD Card. However, alternatives are not always there or do not live up to my needs.
Several examples of some of the apps taking up large amounts of internal storage:
The Facebook app currently takes 11.09MB of internal storage.
The built-in Google Maps takes 10.81MB of internal storage.
The built-in Android Market app takes up 7.98MB of internal storage.
I do not currently have the Adobe apps installed at this time so I can't tell you offhand what those were taking up. But, it was a lot. I even had the Qik video camera app installed for awhile and (at the time at least, since I do not know if any of it has changed) and it only ran off of internal storage.
Keeping all of that in mind, when my phone hits only 10% free space left, my phone starts performing really bad. A lot of this is due to internal caching of apps also taking up space and the need for there to be a certain amount of space free on internal storage. So, you have to also allocate for that. Also keep in mind that a chunk of the internal storage is already allocated for and used by the operating system itself.
So, a phone with internal storage amount of 32GB is not only very welcome but also somewhat needed. But, only as long as I can still store what I can to an external SD Card.
All of that said, AndroidCommunity.com has released some pictures of the new Samsung Galaxy Nexus with the back panel off of it during a side-by-side comparison with an older Samsung phone. A couple of the pictures clearly show the slot for an SD Card.
The Samsung Galaxy Nexus is on the left with the SD Card just to the right of the rear camera as you are facing it.
