I bought a Samsung series 9 thinking it would rival my air, and man was I mistaken. I forgot how clunky, slow, and unstable windows was. I will never stray again.
Windows 7 is a great operating system. It's fast, stable, and straight-to-the-point with a nice layout. The Samsung Series 9 notebook is rather expensive though, and it's a niche product.
Anyways, before I get straight to the point, I consider myself someone who is unbiased towards most things to do with technology. When it comes to Apple, Windows, Linux, or any other operating system, my opinion is based on what it can do for me. I tend to appreciate most of what is there. When it comes to physical hardware, price-points, various technologies, etc, etc... again, I tend to appreciate everything that is there. I own a custom built computer of my own (which I assembled), and the operating system I chose to install on it was Windows 7. I intend to purchase a Macbook Air, and obviously the operating system I will use on that is OSX Lion.
So let's go through this...
Crashing:
How did you manage to get Windows 7 to crash on you? It sounds like you must've been visiting some pornographic websites (somewhere you might get a virus malicious enough to tear your formatted partition to shreds), compiling and running horrible code in C or some other operating system, or messing around with something. Because Windows 7 just doesn't crash; unless if you're overclocking or have a faulty part, I presume (RAM, hard drive, motherboard, etc): However, such a scenario can happen in an Apple computer as well.
Clunky:
This is your own opinion. It's only clunky if you make it clunky for yourself. I am certainly well-organized on my computer. It's very easy to get things done. I have photoshop projects, tons of movies, pictures, games, etc.
Slow:
Windows 7 by itself is not slow. If your hardware is old and horrible, I presume you could be bogged down. So long as you are operating on a minimum of 2GB of RAM, and have a dual-core processor or better, then Windows 7 will run seamlessly. The Samsung Series 9 is obviously capable of doing this, as it exceeds those requirements.
So what could be slowing you down? One of two things:
1. You are expecting the computer to run intensive tasks and hoping it will beast through them like a powerhouse desktop would. Not so. One cannot expect this of a Macbook Air, nor a Samsung Series 9. Ultraportable laptops simply are not designed to do what a decent modern desktop can do.
2. You have bloatware installed on your computer. In this case, simply go to "MSConfig" (you can do this under the search bar), and modify your startup programs. Simple as that. Reduce it down to simply your antivirus, and whatever else that you require. You will then start up with less programs.
Then, uninstall any useless bloatware that you don't need (ex. if you have a yahoo toolbar or something of the like preinstalled).
Then, install Google Chrome, Firefox, or Opera as your browser. Any of these are much faster than Microsoft's Internet Explorer browser, last I checked.
Now you're bloatware free. Be careful when you install a program (ex. let's say you're installing VLC Media Player); when you go to install the program, if you click "accept" and continue through everything, you may be accepting to install an additional little-something-else (bloatware), which you will then have to uninstall afterward.
Windows 7 offers you a lot of freedom, it's stable, it's relatively secure (so long as you're competent with your computer and don't download illegal torrents or visit shady sites), and it's fast. If you don't think so, that's fine. It's not for you. That's A-Okay. But you are unintelligently bashing the operating system, and inadvertently bashing most non-Apple branded computers.
Price-to-performance is what it comes down to for me. I have faith in both the Apple operating system, and the Windows operating system (based on what's currently on the market); I think Lion will probably be fine as well. So what it usually comes down to for me is what is the best offering for the money. When it comes to desktops, building my own is always the best route... there's simply no question about it. When it comes to laptops, that's a different story: The Macbook Air refresh (assuming certain things that have been predicted will come true) appears to be the best route based on the quality of the screen, keyboard, shell, parts, trackpad, aesthetics, etc.
I simply don't buy into this fanboyism nonsense. A product is what a product is. If a company is bad to its consumers on a regular basis, that's a different story altogether. However, Microsoft is not bad to its consumers. A company which I might point at in a non-fanboyist way would be OCZ: They create desktop hardware which is designed to have inflated numbers (SSD's that have high storage capacities and fast claimed reads/writes), they create cheap power supplies with high wattage ratings, they create cheap RAM that looks fancy and is painted gold... etc, etc. But what they do is they put the cheapest of the cheap components in there (B-grade material), and their products fail or break within hours, days, weeks, or months of use. That is an example of a bad company; that is an example of where you can start to get mad at a company for basing its profits off of a horribly flawed product-base. But senselessly bashing Windows... no... that's fanboyism. There's no need to post about that. If you want to compare Lion to Windows 7, and contrast the benefits and the drawbacks... and you conclude Windows 7 is worse based on your factual analysis (which may include your own qualitative opinion), then that's absolutely fine.
