I am NOT hearing good things about W8 from long time Window's users
and even from former Microsoft MVP's (MS no longer does the MVP thing).
Basically its intended as a tablet OS rather than a work station OS.
Maybe with a touch screen monitor that would suit you, who knows?
W7 is OK, different than XP or W2K, but not bad. Its selling point is
that it is commonly available (including drivers for modern hardware) in
a 64 bit version so it supports more than 3GB memory. Frankly I wouldn't
recommend less than 4GB (6-8 even better) for W7. W8 - don't know - but
I have yet to see Ms back down on memory requirements.
If you get into that situation there are free replacements for your
software that work just as well as Ms stuff. Are they a bit different?
Sure, but no more so than current MS software is different than former
Ms versions.
Open Office is a free replacement for Microsoft Office and works just
fine. Thunderbird (email & news) and Firefox (browser), both free, are
arguably better than Windows Explorer so I wouldn't worry about it.
There is always the virtual machine route where you install older OS's
inside the virtual machine software which runs on top of a modern OS. I
installed VMware Player (free) in XP where I run Win2K to run old
software that is no longer supported even on XP, let alone W7 or W8.
No worries, someone will scratch your itch,
