This is an attempt to resurrect the rather entertaining (in my humble opinion) Top 1024 Signs You're Addicted to Your TI Calculator topic with a more general theme, which will hopefully lead to more quality and more quantity of entertaining signs. Please keep it something general (not an obvious reference to something that makes you a technology addict), and could refer to at least one or two other people.

1. You have more email addresses than you can count, but they all forward to the same place.
2. You feel uncomfortably cramped if you're currently using fewer than two (three, four, ....) monitors.
3. The death of a hard drive is an earth-shattering tragedy to you...
4. ...but you have enough copies of your vital data backed up that it's only a minor inconvenience.
5. You have had or currently have some kind of technology cave containing computers, calculators, and/or general gadgetry, preferably lending you notoriety among your friends
6. You vociferously argue either for or against [F]OSS

(Apologies for crappy cell phone pic - I don't feel like digging out my real camera)

29. You're one of the relatively few consumers who needs the bandwidth of a 64-bit processor for memory size rather than processing power reasons.
30. You've ever participated in a vehement argument defending smoe combination of OS X, Windows, and Linux.

45. Non-rechargeable batteries ceased to be cost-effective for you many years ago.

46. Your girlfriend hops on Skype to ask you for help playing the video game you're developing.

Nice setup, but in dire need of some cable management

Also, why do you have 5 speakers in front of you?

Because my bed is behind me. I don't have the room for true surround sound. BUT I've got it configured to mirror the setup I do have, so it works more or less. I tend to lean forward anyway, causing the outermost speakers to be more side than front.

As for the cables, well, that's why I don't turn the lights on

47. The addition of storage capacity to your machines is a happy event for you (2TB for me this evening, but I know everyone gets euphoria from lots of storage space)

51. Dikes and strippers are that you use frequently in your work or play (protip: diagonal cutters and wire strippers)
52. You can explain the difference between Cat-5, Cat-5e, and Cat-6 cabling, and why each needs to be constructed the way it is
53. People who tie a cable's shield to ground or leave it disconnected in wiring, a modification, or a tutorial physically pain you
54. You regularly argue with your computer aloud
55. People no longer bother commenting on the fact that you always have at least one piece of computing hardware with you at all times

My dad has a whole set of Torx wrenches

56. You have outsmarted your company's/school's/university's network admin by breaking through every single layer of security
57. Windows disgusts you because it's too user-friendly and therefore doesn't let you control your whole PC.
58. You carry around rescue CD's all the time.

59. You understand that user-friendliness and control have nothing to do with each other?

60. You don't feel comfortable unless you have a command prompt or terminal to drop to for fast and efficient management and workflow
61. You understand the difference between the -O1, -O2, and -O3 flags.
62. You mock people who use a package manager inferior to (yum, aptitude, pacman, ....) such as (yum, aptitude, pacman, ....)
63. Coffee is your daily substitute for a healthy amount of sleep

65. You are intimately familiar with LaTeX, and no longer bother trying to type equations in Word
66. You are proud that you wear glasses

67. You hate it when people round 2/3 to .67

Sorry, I wrote that during a boring class, and I felt that "windows disgusts you" wasn't enough, so I quickly added that stupid sentence. Never mind.

68.

69. You have a sex bot because nothing breathing will let you fornicate with them.

70. You always wear a usb flashdrive bracelet loaded with DSL

I find your numbering somehow symbolic.

73. The "no user-serviceable parts inside" warning label only serves to remind you that you are no ordinary user.
74. You believe EE to be vastly superior to CS, or vice versa.
75. You consider it a universal truth that projects, coding, and hacking come before sleep, social interaction, and all other activities; you are mystified if anyone around you seems to have a different set of priorities. The only possible exception might be food or caffeine.
76. Your budget reflects the same set of priorities
77. You no longer trust any hard drive manufacturer because over the course of your involvement with technology, you've had a drive from (more or less) every one of them fail.
78. You enjoy math, both in class and on your own
79. You've been known by a nickname intended to be derogatory like Calc Boy (yup, that was me), Loser, Nerd, or the like.
80. You decided that the former was a mark of pride rather than shame
81. Binary (hex, octal) jokes amuse you. For example, 10 computer programmers walk into a bar. The first one orders a beer, and the second of the pair says to the bartender, "why so confused? were you expecting more of us?"
82. You facepalm at such humor.
