Came across this display, and thought R-Pi. It also has a battery so would possibly be ideal for portable PI applications.Though a cheaper option would be this one .

Both looks nice and people have mentioned these types of display before aswell.

Only issue is that displays cost many times the cost of the pi!

Everything is more expensive than the PI. Even when you add up the cost of a keyboard and a mouse even cheap ones will be close to the cost of a PI.

That's nice, but not a touchscreen so you still need a cumbersome input device.  An alternative for mobile applications would be a small tablet or a [insert favourite brand here] smartphone running a remote desktop/VNC.  Has anybody worked out what the possible variations might be on this front (Wifi/wired, Ethernet/USB, Android, iPhone etc)?

KB and Mouse can be had for £10 - less than the cost of even Model A - however displays often cost multiple times the cost of the Pi

Even SD cards are less than the pi - so "everything" is incorrect (unless you add up to get the total amount spend on accessories) - that will be more than the Pi (and I have already spent a few times the cost of a pi on them!)

But this one has a touchscreen. As for customs it depends, but in general if its over 135 pounds then you pay customs and VAT. Below 135 and more than 15 its just the VAT on its declared value.

That's £92 + £19 Shipping (UPS) + 20% VAT = £133.  Not bad, but still a little pricey.  Worth watching to see which way the price goes...

Part of the attraction of the Pi is that many of the parts are likely to be lying around spare in the home. Most people will have an old computer or two in the roof, keyboards, mice and probably one or two old TVs. The only part I have absolutely had to buy is an HDMI/DVI cable. Everything else was lying around. I have bought some SDHC cards but I could have used one from my camera. I bought a card reader and USB hub from Poundland but I could have just about got by with what I already have. So really, my essential preparatory expenditure so far has been £1.99.

This is indeed true - but in my case my old monitor is vga, my old keyboard is ps/2 (seems I could have used a ps/2 to usb adaptor based on what andytuk said but I didn't think this would have worked). I don't have a camera so the only SD cards I had were the ones in my phone - same thing for usb power cable. The only thing I had and decided not to buy was actually a mouse (and ethernet cables - though I was actually thinking to use a wi-fi dongle with the pi).

Also after that first computer I have only ever bought laptops so haven't had much need for peripherals apart from a mouse.

More to the point, where on the planet do 4 vesa bolts cost £3.78? And that USB cable is mightily expensive.

These are too long (you can use a hacksaw?), but much MUCH cheaper for a pack of 25!

The 4 vesa bolts are supposed to be for a min-ITX enclosure and they have notches in the hexagonal heads which are just perfect for containing the 2 rubber bands that will hold the board in place. Sometimes, you have to pay a little bit extra to get the right engineering solution!

And yes, I think the USB cable was from a pack of 4.

I haven't been keeping records (more so I don't think oh gosh I've spent all this money!) but including the Pi I guess I will spend at least £100 on things

@bob_binz: Dixons / PC World Jan Sale, end of line, ex-display model. Seems to still be a current model at Samsung, so I was pleasantly surprised and have a hankering suspicion that it might have been a mistake by Dixons, but I'm not complaining.

Ah yes, 99p for a pack of 25, provided you buy in bulk, but for a single pack that's £1.52, but here is the killer:  Delivery is £5, so unless you live in a town with Screwfix (I don't), your 25 vesa bolts are going to cost £6.52 delivered, just like my 4 mini-ITX bolts cost £3.78 delivered (£2.10 before VAT + delivery).

So for an extra £2.74 I could have got 21 overlength M3 bolts that i don't really have a need for - unless I buy another 5.25 R-Pi's

RMW5, it says computer not a computer system. You can use your TV as monitor, USB keyboard + mouse u can get for £10, 8GB, SD card £5, Powered USB hub £5, a small computing board that you can play with priceless! For everything else there is loansharks …

(prices according to UK stock ebay listing)

How much you wanted to spend is up to you. I personally has a lot of bit and pieces sitting around, so it is cheap for me.

You can use your TV as monitor


Maybe I would if I had a TV, but there isn't one in this house, with or without HDMI, and all of the monitors are VGA. Not complaining, but just pointing out that the "total cost of ownership" is far higher than the headline figure.

Whenever I go up the local recycling centre I am shocked at the TVs and computers that have just been dumped in the skip. You just know that people just fancied something bigger and better and couldn't be bothered to get rid of the old model in any other way.

to RMW5: If someone has no access to electricity then he will have to buy a generator, and the list goes on.  Why buy everything new? like Grumpyoldgit said, you can get most of the parts that people throughs away or 2nd hand.  That is the fun part of the Pi, DIY on the cheap.

The TV/monitor issue in our house is a bit awkward. Our main set has HDMI (the only display we own that does), but I'm not sure how much RPi-time I'd get as I'd have to negotiate it with the other telly-watchers

Alternatives? Well, there's our old CRT in the other room - a possibility, though I bet setting up PAL composite output from the Pi would be a bundle of no-fun (certainly for X11, though it might be OK for console-based stuff). Finally, there's an old 17" flat-panel monitor, which is (drum-roll) VGA-only... think you can see where I'm going with this...

For the moment, the short-term solution would seem to be to plug into the main TV, and try and leap on the "downtime" moments!

Longer-term: in the UK at least, if you're not a "brand snob" (and I'm not, if the product works well), supermarkets sometimes sell small (16-18") flat-panel TVs with HDMI for about £70-80-ish. I guess one of these might make a passable monitor (albeit usually limited to 1280x720 (720p)) so I'd keep an eye out for a good offer on one.

If I heard anyone was trying to get rid of a small (16"-18"), HDMI-equipped flat-panel TV, I'd gladly take it off their hands for them... but then these aren't usually the kind of tellies ending up at the recycling centre

It was just an example after 1 minute of searching. Basically M4x10 pitch 0.7mm. You can notch away to you hearts content with the appropriate hacksaw!

Just for balance, I already have those bolts in stock (in my garage!), I also already had  an HDMI/DVI monitor, USB cables, SD cards, keyboard/mouse, USB hub and wireless adapter. I have had to buy nothing except the Raspi.

So, I'm a best case, you are a worst case. And there are many people over the whole gamut.
