Interesting concept idea, but zelmo said it best. It will have to create an interest in the characters.
Everyone is looking for the next "Friends", "Seinfeld", etc, and it could be possible with this type of set-up. Not to say it wouldn't flop, it does indeed come down to writing. If it was something that blended together an "Office Space" type humor, with a "Seinfeld" character/life interest, it might work. However, they will definitely have an interesting time plots.
Since "Genius Bar" is the working pilot title, I would expect it to change. The downside is if it spoofs on Apple, and tries to make it a running joke. The upside would be if they purchased the rights to use Apple's TM's in a positive, yet subtle, product push.
After all, they're going to have to have some kind of machines in the "store". However it might be a high price to pull off the usage of Apple's TM's. Then again, maybe not as expensive as one would think if it would translate into a subtle 30 minutes of positive product exposure.
Time will tell I guess, but here's to a hope of it being done right. Else if they want to make fun of a computer, there's plenty of PC's to choose from and their "OS" provides an almost endless supply of jokes.
