Went to order the WD PiDrive and discovered a 3-4 week delivery time. Then that razor sharp lightning fast mind remembered I have a 500gig laptop drive and a USB-SATA cable that is powered.
So I am using Berryboot to install Ubuntu Mate to the HD. It says 1 hour plus left to download. Already chewed the corner of my desk off. Not a patient person......
I have had problems with UM. First time it would not expand the file system no matter what I tried. gpated nor fdisk would do it.
Second time everything fine until update and upgrade and it would no longer boot. Both times it was to a Sandisk 16 gig SD. Which works fine with Raspian. Before the update it ran very nicely on the Pi 3. I always liked Gnome 2 and the Wifi and Bluetooth worked great. They are making great progress with it.
Third time is the charm? Right? Please... ;-)
any progress with Ubuntu Mate? Tomorrow Unbuntu 16 make its debut in desktop/server format - but probably not raspi.

Yes it installed to 500gig OK. Ran well on Pi3. To be honest I was as much wanting to see how the desktop was as much as seeing how it ran on a Pi. I have a Mint/Cinnamon install on a desktop PC that I am getting a bit tired of. Cinnamon can get unresponsive at time. I am thinking about just going back to Ubuntu with Unity. It was always responsive on a much lesser machine.
I am running Raspian on the Pis and will probably stay with it. I will probably venture off Raspian once in awhile for adventure with a new OS. New to me I mean. Played with Openelec the other day. Very nice. I have Kodi on my Nvidia Shield console and love it for music.
Anyway. Ubuntu Mate is nice. A good choice for anyone wanting a nice desktop on the Pi. UM install and setup is slow. It is NOT an indication as to it's performance once install is done. Runs very nice once done, for a 1.2gz quad core anyway. Berryboot makes it easy to install to something other than the SD card for those not comfy at the command line.
Is anyone using some of those small LCDs that are available for the RPi? I am looking at the 3.5' but a little concerned about it's usability. I am 65 so weakened vision and shaky hands at times. Do OK with a 4.7" smartphone, most times. Just wondering if anyone has any experience they can relate.

Here is a link to adafruit's forum. There is a bunch of comments there about small screens on a Pi and they have some very good "learn" documents for their small screen products. It might answer some of your questions.
I haven't really dug in deeply, but I have the 2.8" and the 3.5". At first, I didn't like the fact that there was major kernel hacking that adafruit had to do to make them work. I have read, but not confirmed, that these displays' drivers are now included starting in jessie, but NOT the touch screens.
I plan on adding one to the top of my stack. I also swear that one day I'm going to write a small stats app with pygame (I don't run X on my E@H pis), but no time yet...

I have the 2.8 " touchscreen on my Pi that I use to display the image captured thru the eyepiece of a very small telescope with a Raspberry Pi camera board. I do not yet use the touch feature, the display has three micro-switches on one side as well (very tiny tho) for user input (like start/stop recording, zoom in/out in this case). Works quite well.
For displaying a user interface where you actually have to read stuff etc, I would consider the more expensive and bigger official Raspberry Pi touchscreen.

Cool setup! Did you find that the display "just worked" or did you have to use the crazy hacked adafruit kernel?
Also, any updates on any of the Pi Beta Units (gravitational wave, new embedded Wisdom, etc)?
Unreliable electricity company. Had another power outage today. Both my Pi 2B's would not start up again. Seem to have some SD corruption.
Maybe a Pi UPS? There are a few models around. Basically they are a battery connected to the Pi and works as a UPS. I wouldn't expect them to power the Pi for too long at 100% load but it should give it enough time to shutdown gracefully.
One model I saw was just a USB power bank. Plug it into power adapter, plug Pi into power bank and some software monitors the LAN connection. When LAN drops out assumes power has gone and starts shutdown. Others were add-on boards with a battery pack.
I got my Enzotech heatsinks and have swapped out a few Pi2's (replaced with Pi3's) and a B+ (replaced by a Pi2). Apart from swapping the remaining Pi2 out for a Pi3 I am also considering swapping my two Parallellas for Pi3's.
I am thinking of trying to setup a Beowulf cluster with the now redundant Pi2's to play with. I've seen a few tutorials on the web. I am not sure if I can make it do anything useful though. What we need is a BOINC client that can run on a cluster and get the compute nodes to run the tasks.
Thanks for the info and links on LCD screens. A big nope on the hacked kernels. Found a interesting HAT on Amazon and it required the use of their img. Nope.
@bikeman3.1416 Cool pic. Thanks for joining team!
I am looking into this power bank idea Markj speaks of. This is something I have wondered about but not researched. I have a few power bank batteries for tablet and phones. Have run RPi off them before but only wondered if they could be plugged in at the same time. Any links would be appreciated.
I think I may also get a Anker 6,8 or 10 port USB plug in charger and plug into my UPS.
I am looking at improving my infrastructure before adding more RPi. The cabling is already becoming a nightmare and I do worry about corrupted SD cards as it has happened to me too often.
Interesting side note:
The 500 gig laptop drive I hooked up to the Pi3 had it's own power cable. The Pi 3 was plugged into a dual socket plug with a Pi2 that was not overclocked. Had worked fine until I connected HD. Got the mutli-colored box in the corner of the screen. Put Pi3 on own charger and all good. I guess just accessing the HD requires more juice.
