It's better than window clings on a car, in my opinion. My 2007 Gateway "Convertible Notebook" (what used to be called a tablet, back in my ancient college days of 7 years ago) is rocking a black and white Stemage logo (a one-man band, best known for his Metroid Metal series), a stylistic B&W Metroid (both round stickers from some Stemage album I purchased years ago), and an Evol Intent logo--a fantastic drum 'n bass group. <a href="http://cdn.doandroidsdance.com/assets/2013/10/evol-intent-logo.jpg" rel="nofollow">http://cdn.doandroidsdance.com/assets/2013/10/evol-intent-lo...</a><p>They take up about a third of the overall screen height. Having the bleeding red heart separating two black and white logos makes for an interesting aesthetic. My image of the impish young hacker is enhanced by some weird-o stickers. If I was presenting an image of the buttoned-up, sophisticated C-level software architect, I'd prefer an unobstructed view of my generic, high-end laptop's brushed-metal screen backing.<p>Or you could go for the TV approach and just put one big sticker to cover up the manufacturer's logo in the middle of the top.
I don't like keyboard stickers, or stickers that go on the inside area where you rest your hand. It might look cool initially, but they quickly fall apart.<p>Outside of the laptop seems fair game unless you're in an environment that is very client-facing or tends to be a bit more buttoned up (Wall St?) then you should be mindful of that.
I would say don't go too overboard. If it's done nicely, it can look pretty good & draw attention to products you'd like to support.<p>For example, on my Elitebook I have an OpenSUSE sticker & on the palm rest (next to the "Core i7" sticker) I have a GNU/Linux sticker.
I got a new MacBook a few weeks back and have been thinking of getting some kind of cool decal for it after seeing the commercials. My daughter always puts stickers all over her computers when she gets a new one.
Because I'm cool like that ... <a href="https://twitter.com/Clint326/status/497403831899398144" rel="nofollow">https://twitter.com/Clint326/status/497403831899398144</a>
Update: I am a college student studying Computer Science. I am just going to put stickers on the lid, not on the inside/keyboard.<p>Thanks for all of the comments.
