An HD iPad brings with it a number of interesting implications. Apple mobile device users love their video, and high-def content ups the ante for both content and broadband providers. For the content folks, there’s likely to be increased anxiety around content security, and fears of greater piracy. For the ISPs, this is one more way subscribers can bog down their networks. That’s good for getting users to sign on for higher-tier Internet packages, and it’s a potential way to push the metered billing agenda. But it’s bad for operators who are already facing a bandwidth crunch, and need to open up their wallets for further network upgrades.
