Personally I use IB's feed, along with DTN Market Access for historical data, with InvestorRT for charting. It works pretty well for my purposes and is Mac friendly.
That said, I definately think there is a market out there for a single, reliable solution with a low price point, something around the $15/month range all inclusive for emini data/charting at least (excluding DOM as you aren't allowed to aggregate DOM data from CME without the typical reseller agreement). I've given a bit of thought into creating such a product personally, but it's quite a bit of effort. From the technical side I could create it myself as I come from a real-time, high availability software development and systems team management background as well as have some video game programming experience. Some of the same techniques in video game 2D graphic rendering can be applied to charting to produce amazingly smooth, responsive charts that barely use CPU power. It honestly amazes me the marketplace for trading feeds and charting hasn't met this need yet, the building block solutions have been out there for quite a while.
