I think the larger problem is network bandwidth rather than hard device capacity. Even with high speed Internet connection (> 20 Mbit/sec) it can take a couple of days to download the block chain from scratch.
lol. You only have to download the chain one time - forever.
People sit in their living room all over the planet streaming movies every night and you worry about 2MB every ten minutes? Clearly you failed your math A levels.
exactly, 2MB every 10 minutes is basically nothing.
that's about 416 Bytes per second (~3Kb)
even a dialup 56k modem could easily deal with that.
