As I am now attending a 3 day REI workshop at a hotel conferance room and didn't bring my iPad or laptop, just my smart phone.Anyways, getting back on topic ...OK, when I get back home tonight I will re-run the numbers less conservatively (this workshop does not end until like 7pm on these 3 days lol).

Anything for laptops/desktops?

I almost always have my laptop and scanner with me now wherever I go.

I need a laptop solely for me.

That's FLUFF and dishonest to make the average consumer believe they can make that by just sitting around on your laptop and clicking buttons.

So someone books your STR and you see various people coming and going, with maybe backpacks.

Papers start flying off the desk, somebody's laptop with a cash flow analysis spreadsheet catches fire, while you tell them how wrong they are. 

@Jay Hinrichs you are taking me to school....and I forgot my lunch and backpack!

Set up a folder for each deal you do and only share that folder with the specific person you need to.If you want to send secure email, you again have to trust that the person on the other end isn't letting their eight year old install malware on their business laptop (true story) so that it gets infected and all your files get shared with hackers in another country.  

I have a heard time finding the forum even on a laptop or desktop.
