Weigh the cost between buying Windows ($75/PC) and buying a new printer that has new features and is supported by Linux (Epson printers are probably a safe bet there). I would for sure buy a new printer if that is what it took to use Linux instead of Windows.
For me, the decision was a no-brainer. I have 3 desktops and 1 laptop. To put them to Windows 7 would cost $75 * 4 = $300, and I still wouldn't like the performance or customization options in the end. Even the latest Windows is still slow to boot. It requires an antivirus which must be configured, maintained and troubleshooted when it goes haywire, which in my experience is not all that uncommon. Windows remains vulnerable to malware and this is why no computer user should use it at home unless they absolutely have to in order to access a software program. Identity theft and loss of finances can be one result of choosing Windows. But most commonly, users fall into the cycle of buying Windows over and over in order to repair broken Windows. Some may argue they can get a free copy off Pirate Bay, but I wonder how many of those copies contain malware. There is no way anybody can say that those pirated copies are clean. They have no way of knowing and could never know unless they disassembled the binary code and studied it for the next twenty or thirty years, and even after all that time they might not know for sure. With state intelligence agencies now into the hacking game, all bets are off where viruses and malware are concerned. Windows is the #1 target all over the world, because everyone knows it has the most users and is the easiest to compromise and its user-base tends not to be very savvy on security issues.
Linux is great, because I do not have to spend any time out of my day worrying about antivirus. If I need to reinstall, I can, no problem, no need to call Microsoft on the telephone and wait on hold for thirty minutes and then beg the person on the other end to let me reinstall the operating system I already paid for. There are tons of options where customization is concerned. Don't like the way the desktop looks or acts? Fine, you can choose from Xfce, Mate, KDE, Unity, Gnome, LXDE, E17, and the list goes on and on. You download the CD or DVD or Flash Drive off the internet at any time of the day or night and install it whenever you feel like without entering a serial number or begging on your hands and knees to Microsoft. You can even choose from hundreds of distros, although my favorite has to be Linux Mint. I experiment with a lot of distros but always come back to Linux Mint in the end. I guess that means it is well-designed.
My desktop runs 64-bit Kubuntu 13.04, my htpc runs 64-bit Linux Mint Nadia Xfce, my answering machine runs 64-bit windows 7, and my laptop runs 64-bit Linux Mint Nadia KDE. Each seems suited to its purpose.
