Linode is just one of them companies you look at and think.. *Draw dropping*.
To me Linode has it's own market. They're on-top of their game and have a excellent service, with the reviews things people say about them they are worth every penny for there customer care, and the service/performance they offer.
I personally never heard of ZoomVPS or any thing negative or positive about them.
Linode in my eyes, is just amazing though. They don't do promotions really that I'm aware of it, or when they do a promotion it's very rare.
There services are rock solid, and like I said above they're their own market. I wouldn't compare any hosting company to Linode... The prices they list there services at are great to me. Now days with all these companies offering these low end boxs is killing the real vps market.
You have all these run away hosts who try to grab everyone's money with offering $1-3 vps plans and then have alot of people sign up then they fold up in a month. I was actually in a discussion about this over at lowendbox.. Linode's prices for there service is a great price. I wouldn't offer any promotions if I was them, as you cannot go cheaper for what they provide to me. I'm actually getting ready to grab a linode tonight.
I'd recommend you to get Linode. While it looks like Zoom has nice pricing (almost similar to what Linode does offer), I never heard of them personally.
I actually have a Linode acct myself. Mind you though, it's an unmanaged VPS service but then I'm pretty sure that if you're a newbie, you'd definitely learn and deploy your web server needs in just a couple of minutes, if not maybe an hour or two.
I, for say, had no past experiences in dealing with server administration, to be honest. But then I decided to get a Linode acct for myself, basically because I was curious abt their servers and what people are saying.
Being a noob myself, I managed to have myself create a node and deploy it in minutes, if not seconds. Plus, the growing library of Linode is really nice and the community who's supporting it is just so large and helpful.
You can go checkout their forums and irc, you'll see the proof. Personally, I like how whenever you wanted to reboot something from command line, you wouldn't need to have yourself disconnected on putty.
