I did buy a SanDisk 32GB Class 10 card for DML, but it can be used for other things as well. I'm planning on upgrading my USB drive to a 500 GB sometime soon.
I guess that makes two of us...
Now that I'm thinking about it, do you think DM will have a different code to convert the isos now that it runs off the USB? Also I'm wondering is there a way to use one hard drive to split it in half and format each half differently? like if I get a 500GB hard drive I can split it to 400/100 and format the 400GB half to wbfs while keep the 100GB half as Fat32 for DM? I guess we'll find out when it comes out!
