<p>The Pi's user experience is very basic. It doesn't feel that
snappy, but browsers work fine. This is most likely due to having
a pretty basic video GPU.<br>
</p>
<p>Currently I'm working on a drum machine as a micro-controller
project, and have a proof of concept C program running on Linux.<br>
</p>
<p>"touch *.c; time make drummer" takes 0.47s on my i5-1035G1
laptop. It takes 0.53s on the Raspberry Pi 400.</p>
<p>Rendering around 5 minutes of drum loops (a 55MB WAV file) takes
1.79s on the laptop and 1.89s on the Pi.</p>
<p>So for none-demanding programming the performance is very close
to a $1,500 laptop, (except the Pi400 has only 4GB, not 8GB RAM).
Not bad for under NZ$200 for Pi400+SSD.</p>

<p>Hi Richard,</p>
<p>So you're happy with the RPi4 as your daily use machine? I'm
seriously considering this to replace my aging i3 All-in-one. I
assume you went with the 8Gb version?</p>
<p>Anyone else's experience (Mike?) with the RPi4 as a daily use
desktop replacement also welcome.<br>
</p>
<p>Cheers</p>

<div>I use RPi 4 with dual monitors as my main desktop machine
daily. I use a Samsung Portable SSD T5 500GB, bought from
PBtech just about as soon as RPi4 came out. The was
possibly not the cheapest solution but hardware wise its
plug and play and readily available. I reckoned that if I
ever needed more space then SSD's would have reduced in
price. Creating and enabling a swap partition prevents the
pi locking up when Firefox or Chromium have too many active
tabs. The SSD is just used as my home drive as USB booting
from SSD arrived after I had my setup all working. Let me
know if you would like some measurements done.</div>

</div>
<div>Looking at the PBTech web site it looks as though the T5
has been replaced by T7.<br>

<div>I moved to Pi after blowing up my laptop motherboard
using a new chinese usb supply on a usb connected arduino
nano. The supply was well designed but was manufactured with
a sticky foam pad bridging the safety barrier. Consequently
I bought a new laptop motherboard, rpi, and a HV insulation
tester! If I'm ever daft enough to repeat the mistake I'm
hoping to just replace the Pi.<br>

<div>Would you mind letting us know what SSD you ended
up getting and from where? I've looked into this
briefly and I couldn't seem to figure out how to find
one of the Pi compatible ones known to work.</div>

<p>And for something more aligned to the list, I
replaced my Windows Laptop after I discovered my
Raspberry Pi 400 compiled the same C source in
~40% of the time. So I went to the New Years sales
and $1100 later the Raspberry Pi is still quicker.</p>
<p>To reward it for its efforts I now have the Pi
booting from a $69 USB3 SSD rather than usual uSD
card. It now reads disk at 300MB/s.</p>
<p>It is much more capable than expected.</p>
