Some numbers behind Microsoft Corp.'s evolution from Windows 95 to this month's consumer release of Windows Vista:
Common retail price for Windows 95: $89.95
For Vista: Depends on user configuration. Upgrading a PC from Windows XP would cost as little as $99 for Vista Home Basic edition, up to $259 for Vista Ultimate. Suggested retail prices for those versions range from $199 to $399.
Number of lines of code in Windows 95: 11.2 million
In Vista: 50 million is a commonly cited figure, but Microsoft refuses to confirm that officially.
Approximate number of Windows 95 programmers: 200
For Vista: More than 2,000, according to one Microsoft developer's blog, but Microsoft also won't confirm that
This just shows that things are getting more complicated in the software world, before with Win95 things were more basic, you had the OS and then the apps, once the internet hit and everything started moving to a more connected world, we've had to add in support not just for all the new hardware since Win95, but all the new software standards/APIs etc.
They also keep god knows how much legacy code in there still, I really wish they'd draw the line and say we're not supporting things from as far back as 1997 or even older.
Technology advances, so older things like 16bit support have to be totally cut away. This is also why 64bit is moving slower though, I beleave they've taken out lots from the 64bit version of Vista, and you can see it in the fact that 32bit doesn't run nativelly on Vista64, but on what they call WoW (Windows on Windows64) or something like that.
The internet is only part of it, there is more to it then just tossing in IE like they first did with Win95b.
All the added networking code/features alone are enough of a change, things like native IPv6 support now in Vista, stuff like Remote Desktop which they put in XP and improved on in Vista, The new Frameworks and other APIs that work for both offline and online web applications, things like .NET, AJAX and so on. All the support needed to have those web2.0 sites run that weren't around back in 1995 and just a dream.
Then all the added Business network features like VPN and other things that go behond or work in hand with the TCP/IP stack. The point I was making is that with the changes seen since Win95 in terms of software and hardware moving forward, things started to get more advanced and more complicated. Where they at first had 200 coders working on windows, now they have 2,000 or more.
Prices for Vista much to high!!!
