Got together to celebrate daughter getting the Teaching Job this weekend along with my brother(his Birthday)
Now both my daughter and brother are smart cookies(as is his wife)he is a Lead Senior Electrical Engineer(Penn State Grad) and she is a Lead Senior Software Engineer (RIT Grad) and course the Daughter (miss 4.0 ain't no dummy either)
So,they get taking about smart phones, then my brother says----whatever you do (do not buy ANY computer with Windows 8
And goes on to say he 3 weeks about bought a new Dell laptop with Windows 8 and that system is absolutely(unworkable for about anything except looking at pretty pictures like via Facebook etc.) He said he spent a week and a half trying to get that Operating system to (actually work reasonably)---------------------------Nope!
His wife(a Senior Software Eng)-------------tried----------------Nope!
Daughter basically thought -----------------------many of same basic issues on her new laptop boyfriends brother recently bought for her last Christmas.(its useless)
My brother called Dell-----------and said---------am returning it----and "if you cannot supply me with a Windows 7 Pro Operating System------(I will go somewhere and buy from a Company that can)---they wanted to try to get him to take it back and get a $100 bonus ????

They sent him new computer(Windows 7 Pro)-------------all is good!
Now-----for those that have Windows 8--------you can look online and pickup Windows 7 Pro System and Install that on your Windows 8 machine-----It can be found for around $130 or so verses suggested retail of around $320 retail cost.Guess $130 is better than useless machine or spending $$$ for new machine.
but be warned it will void warranty and you will lose any software stuff you already bought and put on it (like say Windows Office Pro etc.)
Bottom Line--------------------If you say when you buy at store(or order online)which you might have to do---- a new machine------unless you can supply me with (Windows 7)---he likes the Pro version best for the $$-----------------------No sale! They might him and haw----but chances are---(It will be done)
Brother said-------------------watch and see (because of how bad Windows 8 is) least in his opinion---pretty soon there will be Windows 9 version which will be about Windows 7 again ??

Otherwise you can keep Windows 8------------------cause it does make for kinda a nice pretend smartphone when using Skype or it does show pretty pitcures???????

Far as performing any serious multitasking efforts------well ???

Again------------just some opinions here-------your results may vary! Ya kinda know your in trouble----when there is no toolbar????
Just some humble opinions only here!
