Heh, heh, heh.
Easier to use, more reliable, faster, and more entertaining. That was some good marketing copy, there.
There were some improvements in Windows 98 (versus Windows 95 OSR2, I mean; comparing it to later systems would be unfair), but these weren't them.
Reliability was basically the same; Windows 98 crashed just as often as Windows 95 and was at least as likely to corrupt the filesystem when it did.
Faster is a joke; Windows 95 performs better every time on the same hardware. (This is normal; newer systems are made for more recent hardware, and they do more, so older systems are always faster. That's true in the open-source world as well, with a few rare exceptions.)
Easier to use and more entertaining? I guess they must be referring to the fact that Windows 98 introduced Windows Media Player, the most impossibly unusable media player EVER (except, possibly, for Apple QuickTime). The only way that's entertaining is if you're watching other people try to figure out how to make it do what they want and laughing at them.
