Are we talking theory or fact or theory made into fact by modding?As far as I know Touchpro2 handles 16GB cards.As far as class I really dont know. To answer the OP yes a 16GB card is enough to hold tons of music,apps,games,and few movies. On mine I have 300 songs, 10 apps, 40 or more games ,and 3 full movies. I have use about 7GB of space with 9GB more to go. I hope this was enough info to solve your question. Anymore questions just PM me.
