You're telling me that a business person walks around with just a USB drive? No laptop/tablet/smartphone connected to the cloud? Come on. That is ridiculous. You are pushing things to the extreme. If that is true that it is an utter failing on that persons part. In the modern world a smartphone can wirelessly output to a projector - no need for a laptop at all.
I've got 128GB of storage on my phone that is connected via Dropbox/OneDrive/Google Drive/FTP/SMB/VPN. I don't bother carrying around a USB stick.
Pushed to the extreme? Hardly. Sure, care to explain how downloading many gigs over the internet is practical? You know, vs a thumb drive that fits in my pocket and stores that much (or more) easily? Plus, if I'm getting on a shared PC to present something, thumb drives are often faster. I have the choice to use either when doing presentations at my uni, and guess what? I go with the one that's easiest and works better, not the one that's "up to date". And that, for me, happens to be a thumb drive. For MANY people, it's a thumb drive. When I see people logging into cloud services to retrieve their presentations, guess what? It often takes longer. Not the download itself, but signing in and navigating to it.
And 128GB in the cloud. Sure, let me smash up half my data cap (Comcast) and take all day downloading/uploading that. (25mbps is already better than average for the US, but that = 11.6 hrs if I ran the numbers right.) Or absolutely murder my mobile connection (5GB cap here). Or use a thumb drive and sidestep the whole issue.
Don't you have a dedicated presentation PC? We've got a dedicated presentation PC but most of the time we just WIRELESSLY connect internal and guest laptops/phones/tablets to the projection system via the internal or guest wireless network.
Some do, some don't I suppose. But wireless? No, there are PLENTY of laptops that can't easily project wirelessly. And the only wireless display receivers I've ever actually seen people use are Apple TVs - and if you've dealt with those, you'll know what a pain they are to mass manage. Clearly not meant for the enterprise. And if you think businesses move fast with projector upgrades, I'd love to know what you're on. Plenty of those projectors don't even have HDMI, much less wireless display (or devices/dongles to enable that).
It sounds as if you are stuck in the late 1990s.
Oh, I'm sorry, does reality offend you? Wired video outputs? Yeah, I haven't seen anything else in almost all places. And Windows can be a slight pain when logging into domain servers over wifi if you just booted and the domain user in question doesn't already have a profile on the local machine. (Though it generally does work well enough. I don't have users rely on ethernet, although I do for setup.) And network cables - yeah, sometimes those are actually easiest. Still the faster/more reliable option for transferring tons of data, and the only way to PXE image in general.
It is safe to say that if you are the type of person that uses a USB mouse with your laptop then the new MacBook is definitely not for you.
USB mice. Oh noes, so outdated, it hurts my senses! Never mind that it works just fine, isn't a maintenance issue (unlike old code/software), etc. And for some people, it's easier. Hell, if a user wants to use a trackball with their computer, why would I stop them? I don't care if it's not seen as "cool" or "new". If it works, it works. I've seen plenty of people who use their laptops primarily at their desk, and usually keep a mouse plugged in. It can still be a perfectly simple use case. Personally, I quit using wireless mice/keyboards a while ago because I'm tired of interference and changing batteries periodically for zero gain. Not seeing a problem with wired peripherals.
In a such an outdated and wire centric world such as yours that is a valid statement.
(laptop with one port = not a business laptop)
Sure, show me all those business laptops that lack any wires. Oh wait, they don't exist, darn it! Actually, wait, they have even more ports, if anything. Maybe that has something to do with what business laptops are actually used for, and businesses wanting functionality more than style/fads? What's next, you decide that making a biz machine razor thin is more important than upgradeability? (Never mind that most business machines are MORE upgradeable/repairable than average, not less. IT departments rather like that.) Probably the same type of guy who would want bluetooth on electronic monitoring racks for remote pumping plants or the like, because a USB cable is too ugly. (Or even 9-pin serial - some 15" biz laptops still have those ports for legacy equipment like this that's still in use and working nicely.) Like anyone's going to like wireless for those.
Needless to say though, why is having ports such a problem? Just put them in the laptop, and don't make it insanely thin. Done. I have yet to see an ethernet port or one too many USB ports kill someone. (Though it'd be funny to see one try.)
