I haven't used my iPod for months, instead deciding to use my cell phone as my music player. Last month I got a G1 (unlocked on AT&T). Overall, it's a great phone, with excellent integration into the Google services, which I use heavily. However, when it comes to the hardware, I wonder if the design engineers actually use these phones. It amazes me that most phones (I'm not singling out the G1 here), even those specifically marketed as multimedia phones, still require an adapter for the headphone jack, unless you want to use the buds that ship with the phone. My G1 came with a miserable set of buds; the right and left cord lengths are different so they tend to pull unevenly and come out of your ears. And forget about jogging with them, they just refuse to stay in place. I think most people want to use their own headphones/ear buds, but then you have to use an adapter - if you're lucky, your phone comes with one - but even then it's one more thing to keep track of and hope you don't lose. The G1 does not come with an adapter, so I had to buy one for around $8 ($15 with shipping). The Motorola RAZR V9 takes the cake - it requires two adapters!

Now I'm sure it does not cost that much to design in a 3.5mm headphone jack. I know space is tight, but these are the kind of details that Apple gets right when thinking about the user experience. I firmly believe the cell phone will be the real competitor to the iPod for mobile music. But if companies want to make any real headway in competing with Apple, take the first step and ditch the headphone adapters.
