I want to get my dad a GPS unit, something he can take while hiking. I'm clueless about these things so if anyone has some recommendations for a nice entry level unit that would be awesome. Just for background, he takes mild day hikes and is pretty tech savvy.
Just from my initial inexperienced/uniformed searching, one of the Garmin eTrex GPS' look good.
Any of the Magellan or Garmin hand helds will be fine. Depending on were your dad likes to hike you may want to consider getting a gps unit that is waterproof. Also you will need to consider what type of software you are going to use with it. I currently use three different packages with my gps unit. Terrain Navigator for back country hiking in the state that I live in, a National Geographics Topo program for other states back country and a street atlas from Rand McNally.
I have a Garmin car GPS, and I love it. I've heard that their hiking ones are excellent also. They're all pretty easy to use, and the maps are very nice.
Here is something about a Trimble GPS unit for the mobile phone.
I don't know anything about this, but Trimble makes professional level surveying equipment and doesn't seem to be as visible in the consumer sector.

I like the types made for running/cycling as it allows you to track all kinds of trivial information that hikers also like to know:
