Does your digital life seem fragmented ?
If you already know what fragmentation is, and are already used to defragmenting your disk every month or so, here is the short version : Linux doesn't need defragmenting.
Now imagine your hard disk is a huge file cabinet, with millions of drawers (thanks to Roberto Di Cosmo for this comparison). Each drawer can only contain a fixed amount of data. Therefore, files that are larger than what such a drawer can contain need to be split up. Some files are so large that they need thousands of drawers. And of course, accessing these files is much easier when the drawers they occupy are close to one another in the file cabinet.
Now imagine you're the owner of this file cabinet, but you don't have time to take care of it, and you want to hire someone to take care of it for you. Two people come for the job, a woman and a man.
- The man has the following strategy : he just empties the drawers when a file is removed, splits up any new file into smaller pieces the size of a drawer, and randomly stuffs each piece into the first available empty drawer. When you mention that this makes it rather difficult to find all the pieces of a particular file, the response is that a dozen boys must be hired every weekend to put the chest back in order.
- The woman has a different technique : she keeps track, on a piece of paper, of contiguous empty drawers. When a new file arrives, she searches this list for a sufficiently long row of empty drawers, and this is where the file is placed. In this way, provided there is enough activity, the file cabinet is always tidy.
Without a doubt, you should hire the woman (you should have known it, women are much better organized ). Well, Windows uses the first method ; Linux uses the second one. The more you use Windows, the slower it is to access files ; the more you use Linux, the faster it is. The choice is up to you!
Are your tired of restarting your computer all the time?
Have you just upgraded one or two little things on your Windows system with "Windows update"? Please reboot. Have you just installed some new software? Please reboot. Does your system seem unstable? Try to reboot, everything will probably work better after that.
Windows always asks you to restart your computer, and that can be annoying (maybe you happen to have a long download going on, and you don't want to interrupt it just because you updated a few pieces of your system). But even if you click "Restart later", Windows still keeps bothering you every ten minutes to let you know that you really should restart the computer. And if you happen to be away from your computer and you didn't see the question, it will happily reboot automatically. Bye bye long download.
Linux basically doesn't need to restart. Whether you install new software (even very big programs) or perform routine upgrades for your system, you will not be asked to restart the computer. It is only necessary when a part from the heart of the system has been updated, and that only happens once every several weeks.
Jump into the next generation of desktops.
You have been impressed by the 3D and transparency possibilities first introduced in Windows Vista, and decided that these unique capabilities were worth a few hundred dollars? You even bought a new computer so that you could meet Vista's (very high) requirements? Fooled you: Linux can do better, for free, and with much less demanding hardware requirements.
He's pretty fair about the whole thing, going so far as to explain the reasons why you probably should stick with Windows. Check it out.
