Anything marketed to "seniors" scares me for the sheer rip-off factor. At $1000 is seems costly compared to other potential offerings on the market today. In fairness it may well have a GUI that is designed to be more friendly to those that aren't computer literate though.
I suppose it all depends on what your requirements are. For some people all they need is a tablet, like an iPad or Nexus etc. For other uses perhaps a PC is required. In either case the cost would be ~1/2 of the WOW. Not knowing what the needs or limitations are its hard to recommend anything.
I sense you have a fear of Windows operating systems. To a huge degree those all went away with Win 7. Run the free Microsoft security tools and they will work just fine. Even XP wasn't that bad. I have an IBM Thinkpad Pentium 3 (!) laptop running XP that I got in 2004 used. It is still going strong and never had a problem, although I will admit I replaced the hard drive to get more space in about 2007. Amazingly I still use that laptop for Internet surfing and dialup or telnet access into remote systems for control!
