Its Trouble...

No one had beards, unless they were from cultures that requirement them.
Cell phones only had digital readouts, and only had actual numeric 10-key pads. Although Treos come out in 2003 with full Internet, full QWERTY keypad, color touch screens, (pretty much iPhone 5's without the fancy hi-res screen; yes, Treo 300 in 2003 out featured iPhones being released in 2010).
Terrorism was the boogie man for everything. (Still is, actually.)
Texting was done with a special kind of pager with a QWERTY keypad or very clumsily on 10-key pad phones that happened to have texting function built-in. Traditional pagers still existed, but mostly used by drug dealers and doctors by this point.
No plaid, unless you lived in the mountains. No flashy patterns, either.
Low-rise jeans.
eBay was a thing back then.
Blockbuster stores were very popular...this is a few years before Netflix's first golden age.
There were still different types of gaming stores before Game Stop bought them all out.
Gearing up for war with Iraq. Blind patriotism was still rampant.
Simpsons reruns played in 1.5hr blocks on network TV.
Trend of kids bring dropped off and picked up at school every day by their parents had just started.
You had an option between Borders, Walden Books and Barnes & Noble for well stocked chain book stores.
Laptops were still kinda luxury items.
Kids enjoying Green Day had no idea that Green Day was a 90's band.
