If you ever accidently drop an iphone or heaven forbid an iPad prepare to empty your wallet. While glass is slick and so called "helicopter glass" is 30 x stroner than ordinary glass it breaks just as easily. I unfortunately know this from experience.

I've been using the iPhone and it is impressive how it becomes natural to use gestures to browse through music files, zoom in and out, etc. I don't doubt now why other makers are following into Apple's footsteps. Then, the iPad is a new sector of products that make use of the same principles, but I still haven't seen a combination of the iPad with the laptop in which the keyboard is present and the capacitive touch-screen is present. I think a disadvantge of the iPad is that it has no way to stand by itself and so I identify it as an entertainment device mainly and not for working or productivity. But if the capacitive touch-screen is put to a laptop, that would allow us to have the best of both worlds. Perhaps this way the mouse would go obsolete. What do you think?

The most startling statement in this article is the prediction that 25% of handsets with touchscreens will have shifted from resistive to capacitive by 2011. Only 25%? Who are these other 75% of customers that put up with those horrible resistive touchscreens? The first touchscreen smartphone in our family had a resistive touchscreen, which was so frustrating to deal with, I would say it was an anti-feature -- a reason to say "I can't wait to get rid of this phone!" The squishy screen was unnatural and not very bright, using the stylus was awkward -- not to mention the stylus was something that could easily be lost -- and doing any touchscreen input with just your finger was difficult at best. Resistive touchscreen is a technology that cannot be obsoleted fast enough!

I would really prefer an anti-glare or matte surface over a glossy surface, so that I don't see my own reflection in the device. The first time I tried an iPhone was on a cold day and it wouldn't operate with gloves on my hand, whereas my old cell phone certainly clicked perfectly with gloves on. Talking about consumer products, I'd certainly buy something the size of the iPad with phone capability and support of Flash.

Touchscreen looks fairly ok. Can it be more advanced with more intutive futures like sensing the movement of hand/palm/fingers and judge the action in advance? In many case, we may never have to touch the screen. We never had good voice recognition system and we may like to add text by writing. Also our eye movement can be very important input. When will we see devices integrating all this futures in one device?

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.
