As a owner of a Z21 I can tell much of what is said in the article is just, simply wrong and misinformed.
The author most likely didn't even touch a Z21.<p><i>DISCLAIMER: I am using Linux full time on this laptop. Some people have issues with the fingerprint or trackpad on Windows - theses are software issues which aren't present on Linux.</i><p>Fan: they're not loud. It's quieter than my MacBook. In fact, I can't hear it in a quiet room.
It's only loud when running full speed; which is rare enough. And that's not louder than the Mac.<p>Trackpad: it's in.. the regular spot.<p>Software: it's loaded with Sony stuff mostly. You can remove or reinstall if you dislike it.<p>Key travel: yes, it's shorter. No I don't see the issue with it, after having used it for quite a long while now. I switch to longer key travel keyboards and back to the Z21 without noticing.<p>The rest is just "look, my iMac design didn't change in 4 years it's awesome, changing design sucks!".<p>Now... let's see what the Z21 has and the others.. just plain don't.<p>SSD: Hello raid0 SATA3 SSDs. Have you ever reached more than 500mbyte/s read/write? Heck, sometimes its going near the 1000mbyte/s sequential. Copying stuff, reading has never been faster. Non-raid0 desktop computer with the fastest SSDs are just way slower. Won't even mention Macs with their subpar SSDs.<p>Screen: Hello 1920x1080 anti-glare screen. How the hell are others not all anti-glare by default ?<p>CPU: Hello regular voltage i7 2620M. The air CPU suddenly look.. you know.. just not in the same range.<p>Heat: what heat? It's extremely well extracted on the side and the rest of the system is at room temperature. Even under extreme load. A problem Apple didn't really solve by the way.<p>Connectivity: USB? check. USB3? check. VGA out for those conferences? Check. HDMI out /w audio? Check. Audio jack, ethernet, sdcard, lightpeak? check check check check. Tell me when the mac book air doesn't need a bunch of adapters to do more than USB.
higher power USB for charging? Heck, check again.<p>Weight? Lighter than the Macbook air says enough.<p>Battery life? Extensible well above 10H via a laptop-wide sheet. Smart. Paris-New York, no need to charge. Of course, the standard battery isn't a let down either at ~5H real time use. (they're both rated 7h and 14h max as far as I can remember, but don't quote me on that)<p>Now with all that, what more could there be?
Oh wait.. I mentioned a lightpeak port didn't I.. so yeah, a 600gr+ device can be added to the desk while you're not on the move.. bundling a very decent ATI graphic card, a bluray drive, and more ports. You can drive 4 screens at the same time, although its convenient only up to 3. (oh noes.)<p>Oh and, does it run linux properly? yep.<p>So it's an expensive device, but considered all the above, it's pretty decent I guess.<p>Finally, the actual bad, and yes, there is some bad:<p>- speaker: they work, but god they're bad. they're terrible. Not a big deal, but still, at this price... the jack is very good tho.<p>- lightpeak will probably not take off, that said, its mostly used for the side device only and serves as USB port, so who cares.<p>- way the laptop sits on the desk you may sometimes find positions where its not sitting properly, if your "desk" is not flat
