Shadowrun Staples, What are they ? Options

[Professeur]

I've read someone that described Dikote as a staple item in previous editions of SR, implying that there are no staple items in SR4. Obviously though there are many.

What do you consider Shadowrun staples ? Let's look at the whole picture though ; staple skills, spells, items, 'ware, whatever.

Here's a few I've thought of

Commlink (obviously), fitted with Firewall 4 at least (6 when possible, and a must-have with hackers, along with a good IC fitted with Analyze/Black Hammer)
Survival knife ! GPS + small hidden compartment + all-purpose tool + wacky flashlight, all in one !
Gecko tape gloves ! Essential if you don't want to spend the BP to get climbing / athletics
Muscle toner / augmentation for the essence-wary physical adept, along with synaptic boosters
Improved reflexes spell
Platelet factories for any combat-oriented PC
SOCIAL SKILLS
Skillwires rating 3 for any Street samurai
Vehicle. Any vehicle.
Fake SIN rating 4, plus 2 other rating 2 spares.
Perception. Always. Rating 3 minimum, with spec.
Dodge (Ranged) + Melee weapon skill. Every runner that has the slightest chance of being on the frontline needs a melee weapon skill, if only at 1 with spec.
Oculars. Either cybereyes, or well-equipped sensors. WITH ULTRASOUND VISION.
Cyberears or audio enhancers.
Smartgun systems for every combat-oriented runner.

That's all I can think of for now. What do you think you can add ?
