I use Linode for several low-traffic sites as well, and I'd recommend them.
However, there's one crucial aspect in which they're different than having a Linux machine sitting in your office (which I also have): for $100 I can put a 2TB drive in the local server. The equivalent space at Linode would cost $1000 a year.
If you have lots of data, Linode probably isn't a good fit. I'd look into Amazon S3 (which I suppose you could use with Linode hosting in front of it, but I'd probably just use AWS if I were relying heavily on S3).
Despite my post, I'm more into server administration than I am programming. Might be why I love Linode. I've helped a couple people set up their Linode sites, and tie it into S3 (and other services) for various uses. The thing I love most about Linode is that it's anything you want it to be.
