A couple technologies that we're seeing today should mature enough to be in widespread use -

Wearables

Expect to be wearing some kind of glasses with an HUD to display messages, directions, or even overlay an augmented version of reality that you've chosen. Imagine AdBlock for billboards in real life, or a virtual 600" TV screen on your wall. This will probably continue into contact lenses or some kind of implant, but 2030 is a bit optimistic for that. The "guts" of the phone will probably migrate to a watch so you don't need to carry anything in your pockets.

Self Driving Cars

Uber, Google, and now pretty much every other car manufacturer are working on these now. Expect car ownership to decline heavily in cities, and legislation being proposed (and heavily opposed) limiting human driving due to the number of traffic deaths every year.

VR

Oculus Rift, HTC Vive, etc will be widespread, cheap, and refined enough that traditional TV screens should be obsolete. The new stereotypical "nerd" image will be a person wearing VR goggles all the time. The interesting question is whether/how Augmented Reality and Virtual Reality will merge.

Medical

Sensors will be all the rage. It's just starting with the Apple watchbands, but having something on or in you that monitors blood pressure, heartbeat, temperature, hydration, immune system activity, or even vitamin levels. Doctors today are using a "guess and check" methodology that will seem silly as we progress into the Information Age. Expect to get an email/SMS/notification that you are becoming ill before you notice any symptoms.

Robots

2030 is far enough out that all the robot research today should be spilling into the workplace. Expect dangerous or repetitive labor like janitorial work, construction, police, etc to be replaced by humanoid robots. Drones should replace UPS/FedEx/Mail/Pizza deliveries, so expect a constant hum of drone traffic overhead at all times in urban areas. Robot "chefs" that produce identical meals every time should be commonplace in the restaurant industry, particularly at chains that have the money to invest. It's a bit early to be expecting robot butlers, but they should be on the horizon by that point. Unemployment will be a serious concern, and ideas like Basic Income should be at least seriously considered by that point but probably not yet implemented.

3D Printing

It's hard to predict just how widespread this will be given that right now the technology is limited to resins and plastics, so home printers can't do much more than make tiny plastic models. These guys have successfully printed clothes, if that trend catches on we could see the death of retail clothes shopping as perfectly fitting garments become the new norm. Once metals and simple circuitry can be printed, it's hard to overstate just how much of an impact 3D printing could have. Or, it could totally flop. We'll see.

AI

Probably still no general AI by this point, but smart systems like Watson and self-correcting neural networks should be able to do diagnostic work like medicine, economics, etc better than a person. No big impact on day to day life other than unemployment, but brain scans that can react to stimulus should start creeping people out at about this time.

Edit: Siri and such

Virtual assistants should be actually useful by this point. Probably still not well developed enough to fall in love with like Her, but with good enough speech recognition and understanding of queries that talking to your computer will be normal. If subvocalization technologies are developed, people will talk to computers all the time. (Subvocalization is currently achieved with a band-aid looking sensor taped to the throat that can map the things you almost say. An implant or ideally EEG built into a headset could perfect this technology.)

Drone delivery won't pass muster from the FAA

Thank you Information Age!
