sony has a few major problems.
premium price without being significantly better
cameras that cant focus for crap with video
propitiatory memory (good for making a bit of extra money, bad for consumer)
these are the major problem areas... and here are my fixes.
make a monitor for the computer 2560x1600, 1080x1200, and make 3 tvs, 70inch, 50 inch, 30 inch only, dont make every size under the sun. consolidating the screen sizes will serve to drop prices while able to keep a higher over all quality, and by hitting most of the major screen sizes you get people to see those 3 instead of 20 different ones all competeing with others of the same size.
for the cameras, make them focus right, and give the user some control on focus when shooting. some times i have to take a picture behind a screen, but it focuses on the screen.
dump propitiatory memory unless you have something to offer, for now, offer sd converters, and phase out exclusive memory.
