a mason and hamlin grand piano about 1930 vintage with wonderful key action and gorgeous sounds.
but given where i live-- a veterans home with folks next door,-- i would get a digital piano 88keys with a superb set of headphones so if i felt like playing khatchaturian's piano concerto or bach's italian concerto at any hour of the day or night i could.
alternatively, i could once again have a super collection of music (vhs tapes, dvds, cds, even some of my old LPs) with an outstanding system to listen to it all.
how about getting back all the libraries i used to have?
airfares and super seats (would need to accommodate a wheelchair) at operas and musical events throughout the world.
would also enjoy eating out at any eating establishment in the world (my choice of place and menu).
transportation et. al. to all the locations i have read about and thought would be cool to see/spend some quality time.
opportunity to chat with any folks (this would include actual and fictional folks of any time with instant translations)i thought would be cool at any time.
several super computers for various purposes with all the goodies one could wish for.
