Analyze your workflow first
Don't get hung-up on "the system"...I did for a year or so (and tried several of them), but my current system uses different things for different purposes. It's all about reducing barriers to entry and creating hard edges (to use DA's phrases). I wouldn't count on Evernote as a storage system. Even if you CAN get your stuff out, it may not be easy. I don't know whether it is, but like you said, it doesn't sync folders to your PC like DB does so you can drag and drop like you already know how to do.
I don't really like DB either b/c you can't edit online. Google Drive and SkyDrive are much better for that (with SD winning out by far b/c you can just edit, create, save, Office format, unlike GDrive). I do like how DB handles images, but I'm sure the others will catch up soon (if they haven't already).
Here's what I use, how, and why
-Outlook: Calendar only (b/c my office uses it). Sometimes I set reminders with Outlook tasks b/c I'm still not good at checking my contexts in the right places. I tend to forget to check "Home" when I get home in the evening for example. Using reminders is okay...the key (per GTD) is to not grow numb to them. So if you find that you're setting reminders and then just ignoring them or postponing them, try a different method. I just use them for the most time sensitive stuff (what I used to write on my hand).
-Gmail: For email (b/c I like the interface). You can redirect email from Outlook (if your using Exchange anyway) and other email systems have other forwarding option. I went to one Email inbox in the past year and I highly recommend it. No more separate email for personal and work. Why make two things you have to check when you can have one. It feels much better to me to process things in one step regardless of the context in which I will deal with them. Don't forget to use the 2-min rule in email...enough soapbox
-OneNote: For all my active and dormant project materials, logs, reference materials, someday maybe lists, Pomodoro forms (I use that tool also), etc. I try to store everything here that isn't a final drive, data file, or is shared so it would make more sense on server. OneNote can store files too, but it's not an idea method. More like a temporary or for reference place.
-Diigo: For web links (because they're easier to share that way...can sync Diigo with Delicious. Xmarks is another good bookmark sync if you want your favorites to show up IN your browser. I've found it's not so bad to have the Diigo page pinned to my taskbar (in IE with win 7+ or use application shortcuts in Chrome). Diigo also has other features like groups, website annotation (which is why I started using it) etc. Free account is pretty good but you can go paid too. It's developed by/for educators but it doesn't have a "grade school feel"...I'm waiting for the corporate world to discover this great tool.
-GoogleDrive, SkyDrive, and Dropbox (plus our file servers at work of course): For file sharing for joint projects. Most people seem to use DB and SD seems used by almost no one yet. GD is in between. I have a SugarSync account, too, but don't use it b/c no one else I work with does. I have a lot of GoogleDrive storage so I setup my SkyDrive to be nested within my Google Drive., and my DB within my SkyDrive. This means that I can access any of those via Google Drive, and can access DB and SD via the SD interface which is by far the best for editing online. I keep track of where files are by having a "File Location" page in my OneNote section for each project.
-Evernote: Only for Next Actions (because it was hard to get a useful NA setup in OneNote that was easy to maintain and I didn't grown numb to...also b/c you can email notes to Evernote and you can't do that in OneNote...minimizes barriers to entry)
So how do I use all this and why did I make it so complicated? Actually, when I was trying to fit everything into once system (Vitalist, Toodledo, OneNote, Springpad) it always ended up more complicated. Some facet wouldn't work well for my workflow or didn't meet my preference for display/interaction. The OneNote iPhone app is pretty smooth but really limited. I didn't like the way Evernote didn't (when I last tried it for this) let you mix text and handwriting in the same note. I even thought about going full paper at one point, but I knew from past experience that that option wouldn't work for me.
I use notebook sections in OneNote as my project lists and prune them monthly. If I don't think I'll be working on it that month. I move it. I do the same with my SkyDrive folder. I really like the month review habit b/c it gets me refocused helps me figure out which bites of the elephant I can reasonably swallow over the next 4 weeks. I don't move project folders around at weekly review unless a project completely and clearly closes out mid-month. I don't do any tweaking during the week (actively trying to minimize that and just go with my system). I have one notebook in Evernote for Next Actions and tags are my contexts (I like that b/c then I can multi-tag if it's needed).
If you think functionally/procedurally,
and test it, you'll find the best solution. If you're planning to use whatever solution from multiple interfaces/devices (e.g., PC, Mac, iPhone, etc) try some basics tasks from each before you commit. You don't want to move everything into Evernote on your PC and then find out that you don't like the Android app for example (or it doesn't do what you need it to do).
PS - Despite my high-tech setup, I still carry a paper notebook for most meetings. I just find it easier to take notes that way a lot of the time. I highlight next actions so they're easy to find when I'm back at my desk or doing my weekly/monthly review, and then I can get them into Evernote. I'll probably move away from that over time, but it beats fumbling with an app, syncing, entering text, being stuck with the computer or phone doesn't work, etc. when all that's needed is a space to write ideas and a way to tag actions. It has a benefit, too...I've found that about 1/3 of the items that I THINK are NAs in the heat of a meeting don't look as important once I'm doing my weekly review (or someone else has done them, or I can delegate them). So it serves as a screening process that reduces my number of NAs.
Hope that helps!
