I studied painting for 3 years at memphis college of art before I got sick of painting and switched to computer graphics and animation. I always preferred drawing. Its more direct, more immediate. I never cared for mixing the colors, diluting, cleaning the brushes (OH! the brushes, always cleaning the brushes!) Back when I was painting, my clothes were always filthy. I enjoy having clothes that are free of stains now!
Now If I feel like painting, I usually reach for markers, its more direct. Painting in photoshop with my wacom is wonderful too. I still crank out an oil painting every now and then, maybe once a year, simply to touch base with the medium again.
All that being said, I encourage you to spend a few years with the medium before moving on to digital painting exclusively. If for no other reason than to appreciate digital paint more!
