We agree on a lot of points. A medium-screen (3" to 4") GPS will live in the car. Using your phone for a second power-hungry function like a GPS receiver is a non-starter. My Garmin iQue3600 PDA/GPS was a reasonable combination for auto navigation and PDA but it's much bigger than I would want to carry as a phone (assuming it had cell capability added). The other niche for standalone GPS units is in the field. When I'm hiking or backpacking, I need a GPS that will run all day and has replaceable (not rechargeable) batteries so on a multi-day trip, I can carry a handful of AA Lithium primary cells to keep the GPS going. (The newer field GPSs have the ability to load and use street/road maps and give turn-by-turn navigation as well, so that will kill my iQue soon.) I agree that a tablet PC may supplant a dedicated ebook reader IF (big if) the battery life can be comparable. Ebook readers with passive (e-paper) monochrome displays will outlast any active/backlit PC display hands down. That's a technological limitation that will be overcome someday. Tablet PCs are fine for pure graphical interaction but typing on a touchscreen keyboard simulacrum is a pain in the anatomy. Netbooks are a better lightweight alternative. (I agree that netbooks and notebooks occupy only slightly different levels in the same food chain.) Finally, to everyone who builds a camera into a GPS, media player, netbook or cell phone, who cares? If I want a camera, I'm going to carry a REAL camera (Nikon D200 DSLR in my case). The camera in my cell phone never gets used and just adds to the cost, power drain and complexity of my phone. I literally couldn't get one WITHOUT a camera but it's the most useless appendage I can think of.

Interesting article, and you had me until you mentioned Tablets will exist between Smart Phones and Laptops. I think you have fallen into the hype of the iPad and are not listening to your own reasoning. Also, I am not sure why you think E-Readers will go away. No one is going to read a book on a Smart Phone and Laptops exist today yet E-Readers are doing really well. If you are going to replace something like a book, it is not going to be a do-all (yet nothing well) gadget like a Tablet. I think E-Readers will just get better leaving even less room for something like a Tablet.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
