What Palm Should Have Announced Instead of the Foleo

Today, Palm announced its new Foleo smartphone companion (shown, next to the Treo). You can learn about it at the Palm website and read some first impressions here, here, and here.

I'm going to reserve judgment on the Foleo until I get some hands-on time with it (you hear that, Palm? Bump me up a few spots on the review unit list, will ya?). It has some interesting points, but I'll admit to being skeptical that the market for this device exceeds a few thousand people.

But it did get me thinking just what would have been a better product (or products) to announce today that would have served a similar purpose (i.e., extending the usefulness of a smartphone like the Treo...or the iPhone)? Here are some ideas that I've seen proposed various places today:

1) Linux-Powered Tablet Treo -- Combine the radio and multimedia functions of a Treo with all the open-source goodness of a Linux kernel and a big touchscreen display.

2) Bluetooth Virtual Display -- Giving the user a better bigscreen view of her Treo's data while only adding a few ounces to her bag seems like an interesting idea. Just one question, though: How do you interact with the Treo if your eyes are blocked by the display?

3) Clamshell Treo -- Proposed by the many who wish the Treo's 2.5" square display was a shade larger yet still pocketable, a clamshell Treo could even have two displays (a la Nintendo's DS) for double the productivity.

4) A Universal Treo-Laptop Interface -- Some have suggested that what Palm really needs to offer is a piece of hardware that would connect a Treo to any PC's USB port and automatically broker data and Internet sharing between the two devices. Imagine a continuous "smart" syncing between the two devices so that the PC could be used as an interface to the Treo's contents, or vice versa.

What's your suggestion? What should Palm have released instead of the Foleo? Or do you think it really is a viable new product category?
