Dreambox 500S VS Dreambox 7000S

I allready have this DB 7000S but i need one more for my other place. And i was thinking of DB 500S. What is the bigest difference between does 2. Can i use Cardsharing with 500S same way as with 7000S. Are there same aplications used or is it something else ?

Yes you can use DM500 to connect to your 7000 but the difference is that dm500 only have 1 cardreader, 7000 has 2.
You need another version of the image also, etc the gemini image for 7000 wont work in 500 but there is gemini images for each box.
