Sure:

I use it to switch between different views, selected in a flexform. I  
know, the controller should switch the views, but the views share some  
code, and I'd prefer to change it in one file rather than 4. It looks like  
that:

[...]
<x:switch by="{useLayout}">
	<x:case label="list">
		<div class="cont">
		<ul>
			<f:for each="{products}" as="product">
				<li><p><f:link.action pageUid="25" pluginName="PiDisplay"  
action="show" controller="Product" arguments="{product :  
product}">{product.title}</f:link.action></p></li>
			</f:for>
		</ul>
		</div>
	</x:case>
	<x:case label="dropdown">
		<div class="cont">
	# you should ignore this ;)
		<x:form method="get" pageUid="25">
			<f:form.hidden name="tx_fiproductdisplay_pidisplay[controller]"  
value="Product" />
			<f:form.hidden name="tx_fiproductdisplay_pidisplay[action]"  
value="show" />
			<f:form.select name="tx_fiproductdisplay_pidisplay[product][uid]"  
options="{products}" optionValueField="uid" optionLabelField="title" />
			<f:form.submit value="{f:translate(key='show')}" />
		</x:form>
		</div>
	</x:case>
	<x:case label="fisheye">
		<div id="fisheye-container"><table class="fisheye"><tr>
		<f:for each="{products}" as="product">
			<f:if condition="{product.headerImg}">
				<td class="fisheye"><f:link.action pageUid="25" pluginName="PiDisplay"  
action="show" controller="Product" arguments="{product :  
product}"><x:fishEyeItem class="fisheye-img"  
src="uploads/tx_fiproductdisplay/{product.headerImg}"  
alt="{product.title}" title="{product.title}" maxWidth="150"  
maxHeight="250" /><p class="fisheye-label  
align-center">{product.title}</p></f:link.action></td>
			</f:if>
		</f:for>
		</tr></table></div>
	</x:case>
	<x:default>
		<f:for each="{products}" as="product">
			<h2 class="orange">{product.title}</h2>
			<f:if condition="{product.headerImg}">
				<x:loadTS  
typoscriptPath='lib.productPic.file.10.file'>uploads/tx_fiproductdisplay/{product.headerImg}</x:loadTS>
				<f:image class="float-right"  
src="{f:cObject(typoscriptObjectPath='lib.productPic')}"  
alt="{product.title}" />
			</f:if>
			<div class="cont"><f:format.html>{product.teaser}</f:format.html></div>
			<p><f:link.action class="more" pageUid="25" pluginName="PiDisplay"  
action="show" controller="Product" arguments="{product :  
product}"><f:translate  
key="productsShow">show</f:translate></f:link.action></p>		</f:for>
	</x:default>
</x:switch>
[...]

But it might also come in handy when iterating over objects, e.g.:

<f:for each="{items}" as="item">
	<x:switch by="{item.layout}">
		<x:case label="highlight">
			<p style="color:red">{item.text}</p>
		</x:case>
		<x:case label="larger">
			<p style="font-size:larger">{item.text}</p>
		</x:case>
		<x:default>
			<p>{item.text}</p>
		</x:default>
	</x:switch>
</f:for>
