Android HW for development: On external storage when the external SD card is not supported?

Question

Context: I am considering to buy the reference tablet Nexus 7 for testing the application during development. I cannot tell you now what kind of applications exactly. They will probably be just portable clients for bigger IT applications (database apps, web-services based communication). I am fairly good in C++, but I do not have the Java hands-on experience. Just studying the official Android web pages.

From what I have learned so far, Android supports internal storage and external storage -- each with specific features. In that sense...

The question: Does Nexus 7 implement the external storage somehow? Is the lack of the external SD (for Nexus 7) related to the external storage as a term at all? Can the lack of external SD be a limitation when designing/developing some sorts of applications?

As Nexus 7 doesn't have a External Memory Storage Card but its internally manage it. When you call Environment.getExternalStorageDirectory() then its return to path /mnt/sdcard/ which is in-built their as a External Storage.

So there is no issue for developing application.
