I have the same problem. I bought the complete kit from Amazon which was supposed to have a 8GB SD card with NOOBS installed. The card turned out to be only 4GB, but that is supposed to be more than enough. I downloaded the most recent version of NOOBS (v1.3.4) linked from the quick start .pdf which I downloaded. I formatted the card using the software suggested (in my case SDFormatter.app for Mac v 4.0). I dragged and dropped the contents of the NOOBS zip file onto the SD card. When I plug it into the pi, it runs an installation, and then displays the choice of OS, and I get similar numbers as mentioned in the original post (2.5 GB needed, 2.3 GB available). So, I cannot install Raspbian. Looking at the SD card using disk utilities, it has two partitions one with a 1.45 GB capacity, with 1.38 GB used, and the other with 33.6 MB capacity.
Do I really need an 8 GB SD card for this to work!!
