Lastpass is my absolutely favorite app. I use it multiple times every day. When I'm traveling, I use it with my VPN on. As the name suggests, you remember one password to get into Lastpass and it holds all your passwords. My tech guy who is hyper security concerned, recommends it. As of today’s date the service costs $24/year. You add the app to your computer, phone, and tablet. When you go to a site that requires sign-in, it takes care of it for you. Your passwords are not held on your device so they can't be stolen.
My most recent analysis of travel insurance benefits and pricing surprised me big time.
World Nomads is the coverage I like. Read Going Alone? Travel Insurance is a Must for my analysis.
I use public WiFi as I travel and I use StrongVPN to protect my identity as I do so.
I simply turn on the VPN and to safely use my credit card or do banking over public WiFi. It's easy to set up - just a bit of software you download onto your computer, phone or tablet. Read VPN for Travel: What, Why and an Easy Setup Guide.
Another alternative for travel insurance, especially for older travelers is RoamRight travel.
Read Best Travel Insurance for Senior Solo Travelers for my analysis.
VRBO.com is like Airbnb however, I have sometimes found better deals on VRBO. I check both. Here's an example. This small studio in a great Manhattan location is just $100/night when I checked. One thing to note about booking on VRBO and every apartment site is the cleaning fee. Apartment sites are not a great option for only one night. 
It took me over 15 years to wear out my first Marmot Jacket
I bought my first Marmot jacket in 2001. I bought the rain pants at the same time and they're still going since they're not used as often. With pitzips and breathable, waterproof, ripstop material, it's a great jacket. Marmot Precip Jacket
And the rain pants to go with the jacket.
I don't use the rain pants as often as the jacket so my original pair are still hanging in. They're light and roll up really small so I take them on most trips that will involve a lot of outdoor time. Marmot Rain Pants

My Swiss Gear carry-on has been through Europe, India and other parts of Asia, and most of North America and it has performed flawlessly. The zipper is strong. The wheels are great - and I've dragged it over seriously tough terrain. I swear by Swiss Gear. Here's a link to a variety of their products.
I loved my Merrells. But since a knee injury it's all about my Eccos.
I've had a number of pairs of Merrell sandals in my life and I have found them to be comfortable and durable. But after wrecking my knee I need a sandal with more support. I now wear the Ecco Yucatan. The Merrell Sandals here. Here's my ECCO Yucatan Sandal.
I walked out of the store onto the trail in my Berghaus.
I bought these Berghaus hiking boots on my trip to the Lake District of England in 2009 and I'm still using them. It was November so I was hiking in the rain and through streams. These boots were a perfect fit from the get-go and waterproof. BERGHAUS Ladies Boots

I love my Vaude Backpack
Unfortunately, this isn't my pack exactly but it's pretty close. It seems that my pack was designed for the Canadian store where I bought it. Regardless, Vaude backpacks are smart and sturdy.
