I sincerely like that idea. The package is so simple.
Think the pricing will scare most people tho. £70 rrp.. maybe if it severely approaches £50 it could be successful.
We could use 100s of these tbh.
See many people liking this just doing a simple diy version tho.
EDIT: Actually - make a silver looking apple-esq version and they'd flood the market, even @ £70.
