I am a retired teacher, so I do not own any of the up-to-date Iphone, Android or other expensive items as you sugguest. With the limited budget which is fixed I have no room for those items.
I have back-ups of the Mach 2 but the problem is that Mach 2 does not run efficiently on the Windows 7. Also, the configuration of Mach 2 is so difficult for me to set-up for any new computer if this one crashes.....
