IS WINDOWS FIT FOR PURPOSE ?

I HAVE OFTEN WONDERED WHY APPLE  MAC COMPUTERS COST SO MUCH MORE THAN WINDOWS OPERATED COMPUTERS. COULD IT BE BECAUSE THEY ARE MORE RELIABLE ?

 I HAVE LITTLE EXPERIENCE OF THE FORMER, BUT STILL HAVE BOTH AN ANTEDELUVIAN MACKINTOSH PLUS AND A MACKINTOSH  LC11 ALONGSIDE THE WINDOWS 7 OPERATED COMPUTER  I CURRENTLY USE. I MAKE NO PRETENCE TO BE A COMPUTER GEEK, HOWEVER CAN COMMENT THAT ALTHOUGH NEITHER OF THE APPLE MACS EVER LET ME DOWN WITHIN THE LIMITS OF THEIR CAPABILITIES, MY WINDOWS 7 OPERATED SYSTEM WHICH WAS CLAMED TO BE AN IMPROVEMENT ON THE VISTA PROGRAMME. FAILS  ONE WAY OR ANOTHER ON A DAY TO DAY BASIS.

 THE 7 SYSTEM SEEMS INFERIOR TO THE XP SYSTEM OF MY PREVIOUS COMPUTER. I REGRET THAT THE EXPENSIVE OFFICE PROFESSIONAL THAT WORKED ON THE XP DOESNT WORK ON THE WINDOWS 7 COMPUTER, HOWEVER  DOWNLOADED OFFICE FREEWARE DOES, AND  COMES TOTHE RESCUE OF WINDOWS 7, WHICH CONSTANTLY ADVISES THAT 'WORKS HAS STOPPED WORKING' ETC ETC.
