FREE ??
WARNING !!
NOTHING and I mean ABSOLUTELY NOTHING is free from MicroSoft!
It will phone home and tell Bill what you were doing all day yesterday, and what your plans are for today. Then YOU can be TARGETED with 'appropriate' advertising. What a crock of shite !
Debian is free and is a rock solid OS. BSD is free and has enterprise solidity. Other varieties of Linux offer various looks and feels, with something to suit pretty much everyone. Most are free.
Under Linux and BSD, there are thousands of FREE software packages, including some seriously heavy stuff. Open Office does all that 95% of MS Office users require and it is COMPATIBLE! --- and its FREE! The Gimp does pretty much everything you need to do with Photoshop, unless you earn your living from photography --- even then, it is a powerful and reliable piece of software --- and its FREE! Linux dumped 8 bit and 16 bit stuff so long ago I have forgotten when, but MS hung onto all their old crappy drivers.
Mostly I use Apple hardware these days. OS-X is based on BSD but there the similarity tends to end, other than for the solidity. I think OS-X costs about £80 to buy and unlike MicroCrap, there is only one version for everyone --- none of your 'HOME' , 'OEM', 'PRO', et. al., or put another way, they charge everyone £80, instead of making a range of prices to worry some into buying top of the range! At hundreds of pounds --- per seat !!
I should qualify this slightly. Apple also produce a SERVER version which is also fabulous, but I don't know its price. FreeBSD is aimed at those who want a great server. PCBSD is the one if you are looking for a desktop machine.
Is this garbled? Sorry, but no more than the choices out there !
