Tell that to the HP Mini 210 that I bought in April 2011.
Synaptic "clickpad" trackpad that claims to support multitouch: Sorry, only with their Windows driver. Not only I don't get multitouch in Ubuntu, but I can't even click or drag/drop anything. Ubuntu 12.04 claimed to fix the issue with clickpads, but it didn't work out of the box, and even after extensive tweaking, some features were still very buggy. In the end, I switched to a laptop that has a traditional trackpad without the multitouch bullshit.
Broadcom wifi card: Works fine once you install the additional driver. But there's a catch: last time I checked, the driver didn't come with the install CD. So I have to download it in order for wifi to work ... but I need wifi in order to download it. Ended up digging out an old ethernet cable from a dusty closet and crawling under another closet to connect it to the modem. Not pleasant!
Of course, most of the problem lies with hardware vendors who don't release fully functional open-source Linux drivers for their gadgets. But since when does the average user care whose fault it is that their trackpad doesn't work? The great thing about this Dell release is that all their drivers are fully functional and freely available as a PPA. Because without those drivers, few of today's latest PC laptops work with Linux out of the box.
