24/7 Internet access is fast approaching but not here yet

[Commentary] The era of ubiquitous Internet access is fast approaching and it can't arrive soon enough. But even though the prospects for ubiquitous Internet are getting better, we still have a long way to go. While current 3G networks are fine for using a smartphone for e-mail, texting and limited Web access, they are not generally adequate for serious use of a computer or iPad-like device. Not only do we need more access, we need faster access and we need more affordable access. My hope is that as the carriers roll out their next-generation services, they will not only provision enough bandwidth to make them truly useful but also will price them within the budgets of most consumers and business users. Until then, most people, when away from home, will continue to hunt around for Wi-Fi access when they need to get online.
