I also have attended few sessions of HANA and they are really good.
Especially developing business applications using HANA studio.
ABAP in Eclipse is one more session which really attracted me.
Looking forward to be part of these new technologies.
Only thing i felt sad is that i couldn't meet anyone from SCN(SDN) because of this busy schedule.
@Mariyln: I saw you on the last day of Teched but couldn't meet as you are busy in an interview session.
