I think that is a hard task. Even someone like me that is ingrained in the technology industry, it can be hard to keep up.
A great technology that i use for staying up to date on many things is RSS.
First place to start
Google Personalized Pages
RSS is an amazing technology that I believe will be a major factor in the coming years. To make it simple, RSS is a way for tech people to provide you information in a standard format to be used in different ways.
The Google example I linked to is what I use. It allows me to list RSS feeds from sites all over the internet and organized them anyway I want.
So, on one single page, I have news from CNN, Crains, technology news sites, even sites like this (look at the top right, there is a link to add RSS feeds).
I could go into all the great things about RSS and it's future implications on business, but to stick with your topic:
RSS is a great technology to help you see on one page news from 20 different technology sites. More information in less time.
But all in all, it can be hard to stay up on technology. Find a good tech company/person that is willing to tell you what is new and not just what they have to sell.
Also, look at groups like NEOSA that is part of COSE, look for podcasts, blogs and newsletters - signup or get their RSS feeds.
Good luck.
