Pi Day is coming - I just might take the plunge
I'd been interested in Raspberry Pi(s) since they first came out, and instead of buying a mid-range laptop for around $300, I think I'll do the Pi thing for a hundred or so.
They bundle these Starter Kits together with a first-times reference book, and that extra cash difference would be available for rehabbing the Transport anyway.
There's a couple of good things that may come from this;
- Challenging my Technical Know-how
- Experimenting it's use as a Media Playback Device (might be useful in building Media Center for non-Tech people...)
- Hands on w/ other branches of Linux than the Ubuntu based stuff I'm used to,
and so on. Who knows what kind of trouble, I mean Fun I can get into...

Re: Pi Day is coming - I just might take the plunge
The Pi and its ilk can be a great deal of fun, and/or frustration. I've done a couple of projects so far: a Pi 2 (I think it was) as a streaming music player for my bedroom system, and a Pi-like board called a La Frite which runs some SDR software for coherent-SDR direction finding.
The biggest practical hints I can offer are: buy a good 5-volt power supply for it, and good fast reliable-brand SD cards. Bad power supplies and bad memory cards seem to be the two biggest sources of trouble for Pi users. Cheap (e.g. Amazon and eBay) supplies and cards are often very problematic... the cards are often counterfeit and/or unreliable.

Good point re: Quality Bits, one if the reasons I'd thought to go with the OEM kit- it's got pre-qualified stuff to get started with.

Re: Pi Day is coming - I just might take the plunge
Well, when i bought the Surface {on which i am currently typing}, i bought a 128-gig Micro SD card to be its "D: drive" at BestBuy {at the same time i bought the Surface}. I don't remember the brand, but i do recall it was a Well Known And Reputable Brand.
I kept having trouble with downloads and saves. Checkdisk and other utilities said there was nothing wrong with the card.
Eventually, just as an experiment, i plugged in a 64-gig card i had lying around.
VIOLA! The trick she was done!
So i bought a store-brand 256-gig card at MicroCenter for $32 ... and it worked perfectly and has continued to do so reliably.
Proof Positive the world is not flat: If it were, cats would have pushed everything off the edge by now.

Buy Samsung or SanDisk.and good fast reliable-brand SD cards
SD cards were originally designed for cameras. In that usage, you see large contiguous blocks of data being accessed all at once. In video recording the "all at once" fades out but it's still large contiguous blocks. And their speed ratings are based on that usage. (Unfortunately, what is often quoted in advertisements is sequential read speed, where what matters in camera usage is sequential write speed - usually rather slower.)
But in something like a Raspberry PI, what matters is random write speed. In randomly sized, and generally small, blocks. ALL SD cards are slower in this usage than in sequential large-block writes, but how much slower varies wildly.
Some years ago I had an (original version) Nook Color booting full-Android off a microSD card (rather than the stripped-down and crippled version of Android that came with the device). Of the (then) commonly available brands I tried, only SanDisk cards were reliably fast enough to not cause crashes.
It took a while but I found a recent benchmark comparison of SD cards that includes random writes (most such articles focus on the large-block-sequential camera usage). Unfortunately, Samsung and SanDisk are practically the only cards tested. Here it is. And here (scroll down for small-block results) is a much-older (2011) test that covers a wider range of manufacturers.

Well, I dun'd it.
I went by Central Computer on the way home last night and bought a small 'kit';
- Raspberry Pi v4, w/ 4Gig RAM
- OEM 5v/3A power supply
- a couple of small heat sinks
- a very thin 'book' entitled ; oh wait, it's just a Quick Start Guide...
There were a couple of ways to go, including a white and red case, but I'm going to ala carte the next few bits.
Oh, and I picked up a quick 32G SD card, SanDisk brand, but I don't have the full Specs w/ me at the moment.
I need to finish downloading the OS image tonight...

Re: Pi Day is coming - I just might take the plunge
Funny you should mention that...
It just happens that I've been thinking on the possibility of getting a Pi to use as a NAS, what with 8TB external USB 3.0 drives going for less than $200...
Meanwhile, I followed your links, then some other links, until I reached this:

Re: Pi Day is coming - I just might take the plunge
Isn't it interesting that the connectors now take up more space than the actual computer?
Don't let other peoples limitations become your constraints!

The Raspberry Pi is a VIC (very important computer)... it has... connections...
Re: Pi Day is coming - I just might take the plunge
True, but it's a bit risky to deal with it. Attitude issues.
It has a chip on its shoulder, you see.

At least, you know you can trust it. It's not hiding anything...
One might say that the Raspberry Pi is the epitome of WYSIWYG* computing...

Re: Pi Day is coming - I just might take the plunge
Update: I've been able to download the Minimal OS installer @ 400meg.
There are two others, both w/ Desktops, the third also including pre-loaded Apps as well.
Something like 1G & 2.9G in size, respectively.
With all the places shut down these days, it's hard to find the Big Pipelines to download from yet still avoid exposing other folks to possible contagion.

Re: Pi Day is coming - I just might take the plunge
Update:
With all of the running around and places closing in the past week, I've had trouble getting the new SD card loaded w/ an OS.
Just now redownloaded a minimal version (Desktop YES, full Apps Suit NO), and we'll see if this one is a good download or not.
[edit] - I'm stalled for a min due to unrelated 32Bit temp laptop file copy/save errors...
