I was ten. My father had switched professions was working on IBM 360/ RCA Spectra 70 FORTRAN. I took a programmed learning course on FORTRAN and helped my dad debug his programs. My mother became a keypunch operator when we moved to Oregon so my favorite past time was the whole family, after hours, went to where Mom and Dad worked. My brother and I would write cards and play with the logic breadboards. I may not have accomplished much at 10, but fast forward 50 years and I am still writing Windows programs. Whee!

Your right about tablets not replacing PC's for software dev, but I have many uses for a table besides entertainment. I am an avid jazz pianist and I use my tablet for displaying music on my piano because a laptop or a PC doesn't fit. I use it to watch piano tutorials and browse for music theory instruction. It is valuable that I can take it away from the piano and study. So no I would never use it for dev, but it is an incredibly valuable tool for learning. It would be nice it my Android had better MIDI software. Cheers
