The monitor can connect to Apple's new MacBook Pro as well as the 12-inch MacBook via a single cable. It also offers power delivery - but users only get 45W of it - so you won't be able to charge the new 13- and 13-inch MacBook Pros from the display itself.

Uh, no.

You certainly can charge a new 13" MBP with a 45W supply — you're just limited to about three-quarters of the rate of its native 61W charger. In fact you can both charge and use it at the same time on 45W, but again, it'll take longer. 

Do the math. The 2016 isn't capable of using 45W just to operate. If it could the battery life would only be a bit over an hour on the 49.2W-h internal battery (Touch Bar model). So imagine that the most intensive real world usage resulted in, say, just 3 hours battery life. That would mean an average power consumption of 16.4W. That would leave 28.6W for charging from a 45W supply, which would bring an empty battery up to 100% charge in well under 2 hours.

Time Machine is designed for hourly backups. In fact as delivered it offers no other choice, although there are third party solutions (e.g. Time Machine Editor) to change that. Once you've completed the initial backup, which can indeed be time consuming, the subsequent incremental backups are quick, in most cases limited by the connection speed to whatever storage you're backing up to. (The same limitation would apply to any other backup software.) The reality is that most people don't change large amounts of file data every day, much less every hour, so the incremental backups are undemanding.

Back when Time Machine was new and computers were much slower than they are today the hourly incremental backups could noticeably slow down the responsiveness of your Mac. That hasn't been a problem for a long time now, certainly not as long as the Mac in question has an SSD rather than one of Apple's dog slow 5400 rpm spinny hard drives. Even my old mid-2010 MBP (with SSD upgrade) carried out its Time Machine backups imperceptibly. 

There are also advantages to using Time Machine to recover data to Apple's own apps such as Mail, Contacts and Calendar, where you don't normally interact directly with the data files. Using third party backup software you have to figure out for yourself which data files you need to restore and where they're hidden. Using Time Machine you simply open the app's view window, enter Time Machine, drill down through the backup snapshots until the missing info appears, then click Restore. It'll go straight into the app where it should be. Just last week I was reminded of how easy and effective this process is when one of my users lost the entire contents of her Contacts. Getting them back was a 2-minute process using time Machine.
