Glad to know that almost all of us have had a sony walkman at some point in our lives.
During my early school days, all i wanted was a walkman!. But my folks were against the idea of gifting me one cuz they thought this will affect my studies

When I was in my 6th standard, i saved up enough pocket money to pick up a 2nd hand sony walkman from an electronic shack. The selling point was an amazing feature called auto reverse! It was my pride and joy at that time in life to listen to it under the wraps during nights and in school breaks. Cant remember the model though, its still there in my room back at my parents.
Venkat's Mr.Sony remark brought back a lot of sweet memories.
Cheers.
