       <title>Things I don&#39;t like in my Chromebook Duet 3</title>
       <link>https://github.com/thiagokokada/blog/blob/main/2024-08-12/01-things-i-dont-like-in-my-chromebook-duet-3.md</link>
-      <description>&lt;p&gt;So this is kind of a continuation from my &lt;a href=&#34;https://github.com/thiagokokada/blog/blob/main/2024-08-05/01-my-favorite-device-is-a-chromebook.md&#34;&gt;previous&#xA;post&lt;/a&gt; talking why my&#xA;favorite device is a Chromebook. In this post I want to talk about what makes&#xA;me this device unhappy, and comment about things that if changed would make it&#xA;a much better device.&lt;/p&gt;&#xA;&lt;p&gt;But before talking about the negative aspects, let me talk about a positive&#xA;aspect that I just briefly talked in the previous post: the screen. It is a&#xA;HiDPI screen (2000x1200 resolution in 10.95&#39;&#39;), that is unexpected bright (400&#xA;nits according to the&#xA;&lt;a href=&#34;https://www.lenovo.com/us/en/p/laptops/lenovo/lenovo-edu-chromebooks/ideapad-duet-3-chromebook-11-inch,-qlc/len101i0034&#34;&gt;specs&lt;/a&gt;).&#xA;It is difficult to find laptops at the same price with a screen that good. At&#xA;10.95&#39;&#39; in its default resolution I find it too small (like 1250x750), but I&#xA;find the font size acceptable at 115% scale (1087x652). Yes, it result in a&#xA;small workspace, but this is not a big issue for what I do in this device. It&#xA;is also only 60Hz, but I thought I would miss high refresh rate more than I&#xA;actually miss in this device.&lt;/p&gt;&#xA;&lt;p&gt;Now the first aspect that I don&#39;t like: the speakers. They sound tiny and even&#xA;at maximum volume it is not really loud. The speakers is the only reason why I&#xA;still keep my &lt;a href=&#34;https://www.gsmarena.com/xiaomi_pad_5-11042.php&#34;&gt;Xiaomi Pad 5&lt;/a&gt;,&#xA;because I like to watch animes/videos before sleep and having good speakers is&#xA;a must.&lt;/p&gt;&#xA;&lt;p&gt;The keyboard has that issue that I mentioned in the previous post: sometimes&#xA;the key get stuck, and I get duplicated characters. But it also has some minor&#xA;issues that I didn&#39;t talked about: the first one is the UK layout that has some&#xA;extra keys that I have no use for, but this also makes the keys that I use&#xA;smaller. Very much a &amp;quot;me&amp;quot; problem, since if I had got a US version I wouldn&#39;t&#xA;have those issues, but an issue nonetheless that gets worse considering how&#xA;small the keyboard is. I am actually suprised how fast I can type considering&#xA;how many issues this keyboard has, so maybe this is a testament that this&#xA;keyboard is not actually that bad.&lt;/p&gt;&#xA;&lt;p&gt;The other keyboard issue is a problem that affects all Chromebooks: its custom&#xA;layout. Google replaced a few keys like Fn keys with shortcuts and replaced the&#xA;Caps Lock with a&#xA;&lt;a href=&#34;https://chromeunboxed.com/chromebook-launcher-now-everything-button&#34;&gt;&amp;quot;Everything&amp;quot;&lt;/a&gt;&#xA;key (that is similar to the Windows Key), while removing Windows Key from its&#xA;place. I actually have less issue with this than I initially though: I don&#39;t&#xA;care too much about Fn keys (except when using IntelliJ, but that is something&#xA;that I only use at &lt;code&gt;$CURRENT_JOB&lt;/code&gt;), and ChromeOS is surprisingly powerful in&#xA;its customisation, allowing you to swap key functionality. I remap Everything&#xA;key with Esc, and Esc for the Everything key, and I can get productive in my&#xA;&lt;code&gt;neovim&lt;/code&gt; setup.&lt;/p&gt;&#xA;&lt;p&gt;And finally, let me talk more about the performance: yes, it is bad, but&#xA;bearable once you get used to. The issue is both the CPU and IO. While the CPU,&#xA;a &lt;a href=&#34;https://www.qualcomm.com/products/mobile/snapdragon/laptops-and-tablets/snapdragon-mobile-compute-platforms/snapdragon-7c-gen-2-compute-platform&#34;&gt;Snapdragon 7c Gen&#xA;2&lt;/a&gt;&#xA;is octa-core, it has only 2 high performance CPU cores vs 6 low performance&#xA;ones (2xARM Cortex A76 vs 6xARM Cortex A55). If it was something like 4x4, it&#xA;would be much better. The fact that the cores are old doesn&#39;t help either.&lt;/p&gt;&#xA;&lt;p&gt;But the worst part is the IO. Not only it uses a eMMC module, it is slow:&lt;/p&gt;&#xA;&lt;p&gt;&lt;img src=&#34;https://github.com/thiagokokada/blog/raw/main/2024-08-12/Screenshot_2024-08-12_20.50.42.png&#34; alt=&#34;CPDT Benchmark results from Chromebook Duet 3.&#34;&gt;&lt;/p&gt;&#xA;&lt;p&gt;I don&#39;t know how much more expensive it would be to put a&#xA;&lt;a href=&#34;https://en.wikipedia.org/wiki/Universal_Flash_Storage&#34;&gt;UFS&lt;/a&gt; instead of eMMC in&#xA;this device, but this is probably the choice that would most increase&#xA;performance in this device, especially considering how aggressive Chromebooks&#xA;use (z)swap.&lt;/p&gt;&#xA;</description>
+      <description>&lt;p&gt;So this is kind of a continuation from my &lt;a href=&#34;https://github.com/thiagokokada/blog/blob/main/2024-08-05/01-my-favorite-device-is-a-chromebook.md&#34;&gt;previous&#xA;post&lt;/a&gt; talking why my&#xA;favorite device is a Chromebook.

Yes, it result in a&#xA;small workspace, but this is not a big issue for what I do in this device. It&#xA;is also only 60Hz, but I thought I would miss high refresh rate more than I&#xA;actually miss in this device.&lt;/p&gt;&#xA;&lt;p&gt;Update: I forgot to say one thing about the screen: it scratches really easy. I&#xA;got my screen scratched after the first day of usage, and considering the price&#xA;I don&#39;t think the screen has a hardened glass. I bought a cheap glass screen&#xA;protector and this did the trick though, even hiding the previous scratch, and&#xA;I have zero issues with the screen now.&lt;/p&gt;&#xA;&lt;p&gt;Now the first aspect that I don&#39;t like: the speakers. They sound tiny and even&#xA;at maximum volume it is not really loud. The speakers is the only reason why I&#xA;still keep my &lt;a href=&#34;https://www.gsmarena.com/xiaomi_pad_5-11042.php&#34;&gt;Xiaomi Pad 5&lt;/a&gt;,&#xA;because I like to watch animes/videos before sleep and having good speakers is&#xA;a must.&lt;/p&gt;&#xA;&lt;p&gt;The keyboard has that issue that I mentioned in the previous post: sometimes&#xA;the key get stuck, and I get duplicated characters.

I thought I would hate this at first, but nowadays I kind&#xA;like it. And it is also nice that it will never get scratched, I don&#39;t care too&#xA;much about the exterior of this device and it is the only device that I have at&#xA;home that doesn&#39;t have additional protection (except the screen protector&#xA;mentioned above).&lt;/p&gt;&#xA;</description>
