Christa is excited about her new Samsung Instinct, which is basically an iPhone lookalike. It has high-speed web browsing, e-mail, GPS, TV, radio…oh, and it makes phone calls too!

Of course, these are all things that phones have done for awhile now. But the Samsung also has a sleek interface and a slim body. As Christa says, we'll have to get her final verdict on the phone in a few months. She's still in the "initial dating phase" with her Instinct.

The wireless industry would love for consumers to get in the "mobile device" mindset -- a term denoting that it's not just a phone, it does so much more.

Soon wireless networks will support unlimited international calls for free. Skype has been trying to get the government to force the cell carriers to let you use Skype on your handset. But there's been pushback because the carriers make too much money ripping you off on international calls. Expect this to change with the arrival of the next wave of cellular technology -- called 4G (fourth generation) in industry lingo.

Skype, meanwhile, has released its 4.0 beta version, and it's heavy on video calling.

When he attended the 1964 World's Fair, Clark recalls that AT&T demonstrated a picture phone. Back then, it seemed like that technology was just around the corner. But video calling never hit the mainstream. Maybe people don't want to be seen on a video phone call. But Clark thinks Skype may be the one to take it to the next level.

Clark's long term goal is to have the capability for show callers to be seen, not just heard, on ClarkHoward.com.
