When I sit down to work on a laptop, I want to open my laptop and start working. I don't even think about a charger until three or four hours have gone by. Your farrago of impedimenta is alien to me, but no doubt if I had something like it, the MBP's relative paucity of ports would annoy me, too.
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.
