Well, Nothing matters to me as I think anything will come will be best.
1. Prices will be remain competitive.
2. Servers will remain awesome.
3. Downtime will be still away from Linode's Dictionary!
But, I am newbie and never hosted on any VPS and want to switch but, I have some serious problems.
1. I am not so aware about Linux and Linux Commands,
2. Don't know how to harden Servers,
3. Servers' security is first priority,
4. Server optimization is second one.
I need linode to host my wordpress blog. So 384mb of ram will be enough to start on Managed server (Since it will be well secured and optimized).
You should bring Shared host customers by introducing some cheap managed VPS obviously with small ram and resources. I run a WP blog on shared hosting and my traffic is still growing.
I run a tech blog which need less ram since I do not deliver Videos or other RAM killer app. For me 256MB ram will be sufficient. If i would come in $10 or $15 per month. If my traffic grow and I need more ram and resources than I will easily upgrade my account. I would switch immediately if you have something like in your portfolio. I think you will need some more Data center to handle.
Why one will sign up for a $5 or $7 or $10 shared hosting if a $10 or $15 VPS will be available.
