This model is a shot across the bow from Apple, but this model also isn't intended for programmers and IT professionals. It's meant for grandparents and a "lay about the house as needed" computer for (currently, rich) people. Apple differentiates things with a Pro line on purpose.

The original MacBook Air had a serious lack of ports and that didn't really trend across their line. It did not come with an Ethernet port, which instilled some major, major outrage. But since then, some of those bowshots have gained a foothold in the industry.

I have a MacBook Pro, and now it doesn't have a built-in Ethernet jack. But it's not a big deal at this point. Even as a network engineer, I only pull out my TBolt Ethernet adapter a couple times a week. The end effect is that I have less cables to deal with on a daily basis and I'm more mobile. I can plop down anywhere at work, open the laptop, get on wireless, and get chucked onto my special VLAN. This is way better than before.

Where I get nervous is things like USB, if you blow out one port you are ok if you have 2-3, but if you only have 1 its a bad day. Not that this is some regular or common occurrence, and typically I use a hub when connecting custom hardware, but it would suck if something failed and it blew out my only port on a machine. Hence my reason for hoping they keep the Pro series a little more flexible.

But for the average person not doing that type of work, your right a simple hub in the monitor is an easy and fairly elegant solution. Effectively a docking station would also be a simple solution as likely the extra ports are not needed when on the go most of the time.
