Here are some links to useful resources for our customers covering Windows, Android & Apple support, online security, etc.
I recommend Dell and Acer Windows desktop computers, laptops & tablets and Microsoft Lumia Windows Phones.
Samsung Android tablets and smartphones are my Android devices of choice.
I use Norton Security and BitDfender Internet Security security software and EaseUS Todo Home Backup software.
I have found that Canon All In One printer/scanner/copiers are normally the most reliable.
