content: Musn't forget the so-called "cost of ownership" questions:unless you can compile and run your own code on it, the maker community will give it a collective "meh" and one/two fingered gesture. So, what will be the development environment, and how much will it cost?what happens if you aren't the developer? If someone else wants to replicate your hack, do they have to pretend to be developer, or pay from Win10, or what?will Win10 + development environment still be free in 2 years time?Or would your investment in time and money be as useless as an MS "PlaysForSure" album (sic) on an MS Zune?

content: Maybe tggzzz should read the article.Only the CPU has changed. Everything else (including the video core, the pinout, the ports) is the same.Windows 10 will support it, and so will mainstream linux, as it's finally an ARMv7 core.And why would you not be able to run your own code on it? That's the whole point of the Raspberry Pi!And the cost is the same $35 as before.

content: RPi2 looks like a proper candidate for a media PC/HTPC replacement: the single core 700MHz ARM was too laggy in XBMC for me to like, I'm interested to see how the more powerful processor with more RAM copes.

content: Quote from: DIPLover on February 02, 2015, 02:24:01 pmI was referring to Win10; I should have made that clearer.Of course everything else remains more-or-less the same, although a recompile will be beneficial to get all the benefit from the ARM7. That's not a problem in the Linux world, but MS's position needs further clarification before it is worth devoting some of your remaining life to it.Added:To confirm that position I've just seen this articlehttp://www.theregister.co.uk/2015/02/02/windows_10_raspberry_pi_2_eben_upton_interview/which includes“What we’re talking about here is Windows 10 for IoT [Internet of Things]; there hasn’t been a statement about capabilities,” Upton explains. “We’re not necessarily talking about PowerPoint or the Windows desktop.Microsoft will make a statement on what exact capabilities they plan to bring to the device fairly soon.”with myemphasisadded.

content: @tggzzz : sorry didn't want to sound so harshWindows 10 is a non-starter for me so I didn't quite understand your angle.The raspberry Pi so far has been an extraordinarily good platform marred by an antiquated cpu. This new core will fix that.Everything the Pi was good at, it will be better. Everything the Pi was marginal at it will become good.And a lot of things the Pi was too weak for, it will become useable.This is a great step forward for the platform.

content: You got to be kidding me!I bought a B+ about a month agoGuess it's only $35I'll wait a couple of more months until the model 2 matures. It's going to take them a couple of months to catch up with the introductory demand as well, I guess.

content: Quote from: DIPLover on February 02, 2015, 03:36:35 pmNo apologies necessary; I wasn't as unambiguous as I could have been.As for your other points, I pretty much agree - the one exception being that the addition of yet another "impenetrable" layer between the cpu/io and the application program won't help beginners feel completely in control in the way they did in the 80s. OTOH that territory is adequately occupied by the Arduino ecosystem, and the RPi is occuping another niche - which is perfectly sensible.I have suspicions that MS is doing this merely to (1) remind Intel the x86 isn't the only game in town and (2) try to get into the IoT space. Once either or both of those have either succeeded or failed, MS may well abandon this initiative.My feeling is that MS probably has a reasonable IoT strategy/offering in there somewhere, but they haven't explained it, and I don't think Win10 "IoT leaf nodes" are going to fly.Windows 10 is a non-starter for me so I didn't quite understand your angle.The raspberry Pi so far has been an extraordinarily good platform marred by an antiquated cpu.

content: if it can run NETMF it should work fine.i've run NETMF on STM32 processors. works perfectly fine. write code in visual studio 2012 and install the NETMF package.compiles directly into ARM code.Plenty of things out there that already do that. (Netduino for example)C has just too many semicolons and curly braces... semicolons cramp up my colon..

content: Quote from: free_electron on February 05, 2015, 12:44:59 amSee for me it's the opposite. I prefer and feel more comfortable in languages that use curly braces and semi-colons, their omission in, for example, python, still feels "wrong" to me after years of use.Stockholm syndrome?

content: This is cool, I might get one. I don't care about Windows, I'll put Linux on it. I never realized these had 40 GPIO pins. Lot of possibilities there for home automation. Arduino is nice but if you have a complex and/or networked program you still want some kind of PC connected to it to run the server. The RPI could do it all in one device.

content: It has less than 40 GPIO pins but it also has I2C , uart, spi still enough for most projects or you can use port expanders.Just wondering if more people have their pi 2 sometimes hanging with a reboot or cold start. I suspect the wallwart PS so will switch to TDk smps but it was sold esp. For the pi

content: Quote from: DIPLover on February 05, 2015, 01:04:02 amI'm the same way. I prefer C++ and similar languages. The nice thing with the PI though from what I'm reading is the IO pins are accessed as files in /proc so you can really use any language you want. I'd use C++ myself.
