Whether you work at home full time as I do, or just use your home office after hours, it should be filled with things that make it comfortable and help \n\nyou be as productive as possible. We've talked to experts and other work-at-homes to come up with advice and a bevy of some of the best and most \n\nuseful products you can buy. Because we're thinking dream office, we haven't let price become an obstacle. You may have to, of course, but this list will give you an idea of \n\nwhat's possible. And did we mention that some of these goodies will give you big-time bragging rights?Why sit when you can walk?All too many of us spend long, painful hours at the desk. Well, here's a way you can work at your computer and get a bit of exercise at the same \n\ntime. The Steelcase Walkstation is a treadmill built around \n\na height adjustable desk that holds your keyboard, monitor and laptop. The treadmill won't replace workouts at the gym \u2014 it doesn't go faster \n\nthan two miles per hour \u2014 but you'll be moving instead of sitting. When you get tired, slide your peripherals to a convenient angle, lower the desk, \n\nand pull up a chair. Maybe the Walkstation is a bit much for your taste, so check out the minimalist design of Heckler's OneLessDesk or a luxurious Kathy Ireland L-shaped desk. One way or the other, you will be seating at your desk, so buy a great chair. And remember, the Aeron isn't the only high-end choice. One chair \n\nthat I'd like to buy is the SwingChair by SmartMotion Technology; the seat, \n\nbackrest and arms all move independently to give you lots of support and comfort. And it's good looking as well. If possible, buy your chair from a \n\nshowroom instead of the Web so you can try it out for size and comfort.The paperless office, sadly, is a myth, but a great scanner will reduce the clutter and maybe even save a tree or two. One of the best you can buy is \n\nthe Fujitsu ScanSnap \n\nS300. The S300 has an automatic feed, scans both sides of a page simultaneously, and best of all, creates searchable PDF files. And speaking of paper, some creep went through my recycling the other week, found a blank check I had forgotten to tear up, and forged my \n\nsignature. Don't let that happen to you; instead buy a good paper shredder. The Fellowes PF-79ci is fast, shreds by \n\ncross cutting so no one will ever reassemble your documents and it has a safety mode that turns off the shredder when hands touch the paper opening. \n\nAnd for style points, there's the snazzy, Black & Decker 15-sheet crosscut shredder. Slideshow: Cool Home Office GearThe world's coolest keyboardsI'll assume you have a nice laptop, but who wants to peer at a relatively small display for hours at end. Not me.If money were no object, I'd buy a really big monitor to hook up to my notebook. Two good options: The Dell \n\nUltraSharp U2711 27-inch monitor for PCs, and the even larger (30-inch) Apple Cinema HD Display for the Mac. Or you \n\nmight want to buy two smaller monitors and use the dual-display function built into Windows to create a huge virtual desktop. You already know there are lots of decent ergonomic keyboards around, but let's face it, they are BORING, and we're talking dream office here. \n\nSo take a leap and check out these ergonomically correct \n\nsteampunk keyboards. Talk about cool. The designer, a dude named Richard R. Nagy, also known as Datamancer, will make you one or sell you a \n\nkit so you can do it yourself. Trust me. You will definitely impress your friends with one of these. And finally, I've got two recommendations for high-end sound in your sanctum sanctorum. First, there's the Wave music system from Bose, with an iPod\/iPhone dock and multi-CD changer. Or consider buying the Sonos ZonePlayer S5, a one-piece system \n\nthat plays music from the hard drives of your PC or Mac, and from a number of different Internet services, including Pandora, Rhapsody, lastFM, \n\nNapster and Sirius.
