The best parts are the natural language inputs and inherent connectedness with data. These are going to eventually become expectations that you'll have interacting with computer systems in general. Having a computer interface that lets you say, find out who in my office is sending the most email, in a one liner is the next logical step. Including and understanding your company / personal data in the way Wolfram Alpha understands its curated data is the missing link. I'd be really interested in integration with enterprise resource planning software, and customer relational management software for big corps. For web firms an interface to salesforce.com, an interface to your web analytics data, your support ticket dashboard, your web marketing data. I imagine being able to simply ask questions like how does the weather in my customers location impact my conversion rate? Or other poignant questions mixing internal and external data seamlessly.
