I have tried a while ago Mandrake Linux, but I was not satisfied with it. Had to return to Windows as I use computer as tool...
The Windows XP was good choice (although Windows 2000 was good too) and after I got very stable system, it is not more possible to use on new computers.
The Windows XP under VirtualBox under Ubuntu works much better than stand alone.
Other big advantage of Ubuntu is that this OS is energy saving
, the battery on laptop lasts at least double more time.
In addition, even Windows XP in VirtualBox become energy saving...
Now, not much choice left, if I want to keep my instruments "alive":
1. Microchip ICD2 (not more supported, was advised to buy ICD3).
2. TiePie HS3-100MHz USB scope.
3. Janatek LuLa USB logic analyzer (16 channels).
When was trying to get my ICD2 back in function, the advice is to buy ICD3 and MPLABX. Why I should buy new instrument, install new software and port my projects in new environment? I have old instruments and old software and I'm quite happy with it.
I bought new Dell Inspiron laptop with preinstalled Ubuntu and I tried to install XP as separate OS on it. Unfortunately, it is not possible (blue screen)...
Started with Ubuntu two years ago and now I have XP machine running under VirtualBox and got all my instruments back.
Definitely is the best choice Ubuntu as the software is mostly free, no need for antivirus software, etc.
In addition, the missing serial port has been sorted with FTDI USB Serial Converter, which (after installation) is possible to use under DOS box, under Windows XP inside VirtualBox under Ubuntu Linux (currently running 14 TLS).
Now I'm saying that (after installing Wine and VirtualBox) this OS is so stupid that it doesn't recognize that particular application is designed for use under other OS.
I don't have smartphone, but I'll buy one, when it will be with Ubuntu, not Android.
Don't want to bother with Google accounts...
I like that Ubuntu store doesn't ask for registration.
So, definitely Ubuntu is my choice.
