The reason why I was going for Windows I suppose is because It recommended something with an interface familiar to you. And to be honest from experience I tend to incline towards paying a little more for a better service rather then finding out im missing something I would need (the cost is not a problem for me so to speak).
I would suggest paying a bit
less and getting a far
better site by using Linux (Basic or Business plan). Frankly, Linux + Apache server delivers a more capable and stable platform than Windows + IIS -- at lower cost (no MS license fees). Not to mention that LP's support seems to be much more experienced with Linux support than Windows.
As suggested by @Tristan, go Windows
only if it provides something that you absolutely, positively can't do without -- say, MSSQL, or .Net services. That means that you've already selected the underlying technology, to support a given application you've chosen to use, or that your developer is comfortable with. If starting a basic (X)HTML/CSS/JS site, go with Linux -- there's absolutely no advantage to using Windows.
