6 Months Worth of Use
I've used Elementary OS Freya for over 6 months, and I'd like to share my experience here so you can make a more informed choice.
Short answer is: wait until it comes out of Beta. It's not stable.
In the office environment I have, it's predominantly Windows PC's and Servers that make up the infrastructure. Myself and my assistant both run Linux. Up until I used Elementary, I used to run Debian 7 until I had a period of downtime where by I could afford to try another Linux distro out. I chose Elementary based on a glowing reference from a friend of mine who was trying it out. At this point I must add that this same person used Elementary for a month and switched back to Windows.
At the beginning, it worked absolutely fine. Fairly speedy, fairly easy to use, very Mac OS X like in the way things are laid out and designed.
The mail client (Geary) is lovely. Very simple and elegant - but would not work with my Exchange email account. In this case I had to switch to Thunderbird, and it works fine. Midori is the same, looked alright but it was an absolute pain to give it Flash support. I'm not even sure it has it even now, as I installed Firefox and have used that ever since.
The chinks in the armour start to appear about 2/3 months in to using Elementary. What started out as a rare event, but now happens increasingly often, the file manager wouldn't list the folders held on our Windows server. This meant a reboot of the system. Furthermore, the system will, at points, crash/hang. Doesn't happen often, but if it does happen it happens when the machine first starts up.
What has to be remembered with this distribution is that it's in Beta, so these issues are to be expected. However, I feel the beta period is too long for something that is given out as something that can be used by the general public. It'd be far better to still use Luna as a finished product and wait for Freya, but I'm not in charge of their development cycle.It's also worth noting that my assistants Debian 7 installation (which is essentially my old desktop) has not put a foot wrong.
I want to like Elementary, I really do, but it's just not that stable for me to have full confidence using it. I'm stuck with it now until at least January while I finish off another project, but after this I will resort back to using Debian 7.
So, please take my thoughts in to consideration when you're chosing your Linux Distro. Get Debian.
