I make sure to maintain my keyboard being clean by making sure my hands are clean every time I use them. Sadly over time they can get dirty which just means I have to take it apart, and wash it. I've only gone though one keyboard, and the last time died because of a defect in the usb/ps2 aspect of it so I had to replace it. My roommate goes though keyboards every year I think it’s because he eats over it and basically lives at his desk while taking little or no care about it. His last keyboard was growing mold on it which is how that ended, I told his wife to stop buying wireless keyboards for him if he’s going to go though them every year.
Now if we were talking about mice, due to my gaming habits I think I've got though 6 of them, sadly the left clicker wears out, and I've tried many attempts to fixing them in the past with no luck, sadly my first mouse died for other reason but it could be the issues I have with mice now are because of the brand since I switched after that first one and had so many issues since.
I can only speculate that the 2-23-87 refers to the date they completed this prototype and being so close to launch is why there are no differences from the released version. Again I'm speculating.
which means that he has no idea if it's really the prototype or not. He's just trying to make a quick buck of anyone who will read the headlines and not the fine print.
Super low bandwidth dial-up and super high latency wireless or satellite are not alternatives to actual broadband access.
Last I checked even Dialup is considered Broadband "Signals over such a range of frequencies." which in some cases your right is a low bandwidth option but if you choose to live in an area that doesn't offer what you want then move. Wireless and Satellite have come a long way, I'd say they are very good options inplace of dial up. My point is that they "are" alternatives it's your "choice" not to use them or consider them useful.
Variables don't; constants aren't.
