I got a new phone a few weeks ago. It is identical to my old phone, (thanks cell phone insurance), and they carried over all of my contacts. But they didn't carry over my ringtones or settings.
Now, every time my phone chimes, and it is just out of my reach (ie- I'm too lazy to get up and reach over for it), I have to check 3 different email accounts, Facebook, and Twitter on my laptop (which is always in my lap) to determine where the message came from, or decide it was a text. (At least I know what the actually phone ringing ringtone sounds like. (It is still the NCIS theme song. Which is only confusing when the phone rings when I'm watching NCIS on TV.))
These are my 21st century problems.
What are your 21st century problems?
