They say no computer needed.However you really can't really get what the radio has to offer unless you do.The screen is quite usless in a sunny car,which was found out today.Also noticed no real difference if using duckie or top of roof mobile mount.Vocabulary is differant-Law instead of police,also Federal and goverment which, state or what.Otherwise like most advertisements,gets you motivated and then "is this all their is?"Good luck,when cometh HP-2?
OK, not to point fingers but your post illustrates who the HP-1 is NOT aimed at. If you have umpteen years experience with radios and scanners then of course it doesn't fit your needs.
If, however, you don't know a scanner from an iPhone then the HP-1 is right up your alley.
A first-timer doesn't know it's "different" from other scanners 'cause he's never used one.
A first-timer doesn't go "is this all there is?" because he's coming from NOTHING and anything is a vast improvement.
A first-timer may not ever use it in the car and if he does, he has nothing to compare it to as he's got no history using monochrome LCDs so he'll never notice it's harder to read than XYZ scanner. He's never seen or used another scanner.
I have used other scanners in ancient times (before trunking) and I remember when there were no LCDs, just dim red LED or flourescent displays. The HP-1's display is as good as a touch-screen can get - at least comparable to touch-screen GPSs I've owned.
So if you've been scanning since before the CD was invented, no you're not going to like the HP-1. However, you're probably averse to change and have bad eyes, creaky joints, poor hearing and are on Medicare so nothing we say will help you love your HP-1.
