Not just "everything was new" but also "everything was better" (well.. except the stuff that wasn't and failed horribly soon after launch). You bought a computer, and (if you had a money) you bought a new one after a few years and the change in performance, graphics etc. was HUGE. Kilobytes of ram went to megabytes, cga, ega, vga all brought huge improvements, then came many 3d variants, storage went from floppies, to a few megabytes to gigabytes.
And now? Have a 5 year old mid-range computer? Buy some ram, and you get basically the same specs as the new ones, but with a slightly worse CPU. Everything (except the newest games) still works, and the biggest resource hog (especially ram) is the browser, which still shows sites with same amount of info as it did in 1990s, but somehow that autoplaying video ad needs a few more gigabytes of ram.
It's still great for my wallet... but I haven't opened a computer magazine (or well.. a youtube clip in modern time) and said "damn, I want this!" in quite a while now (at least not regarding computers).
