THE HOU!

THAT WINDOWS BUILT"?

s ii over? I believe it

probably is. With a

carefullookaround,

I tried todetermine

just how much the

world had changed

with the release of

Microsoft's new OS,

Windows'95. Afterall themedia hype. I expectedthe

sun toriseintiiewest,birds to fly backwards,peace to

reign throughout the world, and even more. Oddly,

nothing much seemed to change.

Okay, thai isn't entirelytrue.Therewerea lot more

messagesin the'local'messagebaseon ihefiliSIuseto

accesstheCommodoreFidoneIechoes. Lookingthem

over, I noticed 3 trend... all ofthemessages regarding

Windows'95 seemed to benegative! i checkedcloser.

Sure enough, I couldn't find a single positive response

postedconcerningtheOSreleasethatwouldshakethe

computing world to its foundation, What I did see,

though, wasn't entirely unexpected. Users who had

found some way to crash their hard drives during

installation, others with applications thai they could

not get to work right anymore; not surprising at all,

this stuff happens all the time when users upgrade

theirOSandapplications,;mdthefact thatquiteafew

more users were doing this at the same time easily

accountedfor theextradose ofproblem messages.

But I did find something I didn't expect several

MS-DOSuserswereactuallydecryingthe newrelease,

and complaining about the endless upgrading that

kept emptyingtheirwallets. I had tochucklea littleas

[thoughtbackonsimifarsentimentsexpressedinpast

issues of Commodore World. But being Ihe polite

tetecommunicatorthatlam, Ibitmytongue(lingers?)

and avoided posting any "I could have told you so"

business they had hoped it would. By the weekend,

most retail computer stores were back lo business us

usual, which means slow this time ofyear. Odds are

that thiswas mostly due lo the majorityofsalesgoing

through mail-order for all those software upgrades

andadditionalRAMfolksneeded,astheapparentlack

ofinterestattheretaillevelhadn'taffectedMicrosoft's

sales projections lor Window's, which appear lo be

righton track.

Meanwhile. Microsoft head honcho Bill Gates got

Now, Windows'95 really can't be all that had. Like
