The alarm clock will still be on my wife's side of the bed and will probably be a cheap Timex battery powered unit with buttons that are hard to press and a crappy display and annoying beep for an alarm. She will still the voice that pulls me from my sleep,
We will have the same shower with maybe an upgrade to the shower head. I don't see a need to upgrade our Thermosol shower control as it seems to do a fine job at at temperature control. We will still live on the east coast where water is not so much a valued commodity. We tend to take short showers, so this shouldn't be an issue.
I will still have a phone and a computer. My computer might look more like a tablet and syncing will be faster and easier, but I won't be plopping my phone into a docking station at my office. Dropbox or Google sync seems to give me that functionality today.
I expect to be swiping and typing. I don't think I will be gesturing into the air which seems to require to much energy. I still expect no more than a 30 inch display on my desk, although the screen and tablet computer might be flexible and thin. I doubt the metric system will take hole in the U.S. I will still be driving at 75MPH on roads with a 65MPH speed limit. My car might have more voice controls and a heads up display, but I suspect it will be a hybrid that runs on electricity and natural gas rather than gasoline.
I will still expect a paper or card menu at the restaurant and a live waiter. The card menu could possibly be a flexible computer, but it will have to look and feel like a menu card to be acceptable.

My kitchen appliances will be very high tech with touch displays, but their function will likely be the same. We might have some unforeseen replacements for microwave ovens, but I doubt it.
In essence, I don't expect things to change dramatically. I expect I will have multiple devices that are all synced together (I have that now, so why would it be different 15 years from now). Siri might actually work and be useful by then, but I will still only use it in the car. I won't want to be shouting out my preferences or requests in public for all to hear.
