This reminds me of the Charter ads that are a desperate attempt to save cable and land lines. Like the sentimental one showing the soldier calling his family and them all picking up the phones in their individual spots to talk to him. This Ad is targeting the very large "Everyone has a cellphone we don't need a landline" crowd. It negates the idea of conference calling on cellphones, and tries to convince the viewer that there are times so important that it's worth $50+ a month for a land line, despite the fact that you already have a cellphone your more likely to use.
Just like this Ad, negating the fact that he probably had WiFi at work (but you think that was intentional? We can't forget a LARGE number of smartphone users are oblivious to technology, maybe this tries to subliminally convince them that you also can't use WiFi and talk?), and trying to convince people that, despite the downfalls, it is necessary that you have talk and surf capabilities.
I, for one, use such a feature all the time. But, I could also live without it. What I COULDN'T live without is the higher speeds. There are other advantages to GSM too, like international travel (Dominated by GSM), but those are useless to me. I also really would miss having a SIM card. More than once I've had a phone crap out on me, or just die at an inconvenient time. I can pop my SIM card into one of a couple of oldie but goodie cellphones I have in a drawer if something happened. This is all more evidence that the GSM vs CDMA debate is 6 in one hand, half a dozen in the other.
Honestly, if AT&T was as reliable and committed as Verizon, they would be the hands-down winner. There is no "advantage" to CDMA that I am aware of (if not, correct me, I'm sure someone will), but the CDMA carriers seems to be better in this country, and it's a shame.
Where I live, I have fantastic AT&T service. 5 megs down, 2 megs up, I can get online / call anywhere (this is an hour west of the St.Louis area). By contrast, next time you see Verizon pop up one of their pretty maps, see that BIIIIG white spot in the middle of the US (eastern side of Missouri), yeah that's me. Nada. Nothin. Not even a call out. In fact, I had a friend who moved out here and got out of her Verizon contract because she had 0 service, and Verizon agreed to let her out of it because she was in a "no-service area". BUT, ANY TIME I've traveled outside of this area, the service sucked. Royally. I hope this competition will force AT&T to get their act together. It can't hurt, right?
(I should also mention I can't remember the last time I dropped a call. Go figure right? If they can do it here, why can't they do it anywhere else?)
