When I sit down to work on a laptop, unless I'm just stopping to check something for a couple of minutes, I usually want to plug in at least my phone (since publicly-available WiFi is not really a thing, often I have to USB tether to get usable connectivity (I could wifi tether if I had to, but this kills the phone's battery)), mouse, headphones, and AC adapter. I'll pretty frequently want to use an external storage device like an SD card or USB hard disk and if I'm in a real office, I'll usually want to plug in to the physical network (even non-Apple portables don't include this port usually anymore, so that's another USB port occupied) and use an external keyboard.

That's just me. A few of those things could be transferred to wireless peripherals, but not all of them, and wireless peripherals usually suck pretty bad. I have a Bluetooth headset that I try to use in the field occasionally and it's a nightmare switching between A2DP and telephony modes. I could switch to a wireless mouse, but then that's batteries and many of these take up a USB port anyway with a proprietary dongle. I don't usually carry a full keyboard around with me so I just gotta use what they have in the office, which again, even if it's wireless, often occupies a USB port.

To me, this is serious. I don't think I'm doing anything super special; I'm definitely not writing custom firmware for esoteric embedded devices from Starbucks or anything like that. Just your everyday developer and sysadmin.

Now, if I put a lot of effort into it and decided I was going to live on a MBP and therefore needed to keep my usage restrained to one or two USB ports max, I may be able to come up with an arrangement that works, but it's by no means the default; I most recently tried to live off a MBP for 5 months in the first half of 2013, and it didn't work out (the lack of ports was a constant annoyance, but not the impetus behind the change). I swapped it for a Thinkpad and was much happier. I find this happens to me every time I try to live off an MBP. The most successful run I had was 2006-2008 where an MBP was my sole laptop and I did a lot of remote work, but it was not really pleasant and I had a desktop that I used to supplement.

To be clear, I have bought 3 Apple laptops over the years of my own free will and used a few more that were owned by employers. It's not that I hate them (in fact I continue to be astonished by Retina displays, which I was sure was just going to be hype before I saw it in person, and wish PC makers would catch up), but I just don't think they're good workhorse machines for people who do real work. I think they're mostly a fashion thing that people force themselves to live with. I'd love to have one around the house as a casual computing machine, but it's hard to justify dropping $2k for the setup, when again, there is real work that would be better served by the same investment going to actually useful equipment or to labor.

I just don't really see a reason to force myself to heed Apple's insistence that while I think I may want more than two ports, I really don't. Even the way I use Apple hardware usually pisses off Mac devotees -- back in 2006 I made some permanent enemies out of a few acquaintances that were stunned I would be voluntarily using Fedora on a MacBook Pro. They kept repeating that they'd totally understand if it was a PC, but if I had to use Linux on a Mac, I was most likely just a retard who couldn't grasp the beauty gifted to earth by Humanity's Eminent Genius Steve Jobs. They continued this hostility every other time I saw them. Pretty bizarre.
