Summary: Compared to other units that I have bought and returned in the last few months, I have found my solution. Why spend hundreds of dollara (I found it on a rare sale for $399) on a stand alone GPS unit when you can purchase this unit that will also be a pocket PC, multimedia player? I have already downloaded software that will allow this unit to watch AVI files which the Windows Media Player on the unit will not allow you to do. No matter, like any other computer, you can add software to meet your needs. The unti has ample 2GB internal ROM with only about 3/4 filled with operating and other software. Plus, it has the SD expansion slot limited only by the size of your SD card. It is lightweight and versatile making me take this unit with me rather than leaving it in the car as I would with a stand-alone TomTom unit...it truly is a travel companion.

Summary: This device is a must have if you travel a lot, get lost a lot and enjoy having a pda and GPS device in one small package.

I originally had a Dell Axim X50V that I then added an external SD GPS device too. It worked, but the GPS stuck out and was terribly fragile. This unit integrates the GPS unit within and it rocks! There's an external antenna hookup for better reception, but I have yet to use it and I get awesome reception.

TRY THIS IF YOU OWN IT: Sit in a window seat on an airplane, startup TomTom and within a few minutes you will be tracking your flight progress across america at 550 mph! That's how good the reception is even without an external antenna! My neighbors on the planes I fly are always intrigued when they see the little arrow flying through cities and towns. You will even know what gate you're taxiing into because TomTom has the airport layouts on its maps. Regular street navigation is awesome as well with the newer 6.0 version that this one has.

The joystick pad is a little annoying and I wish they would have just made separate buttons, but it's not terrible. I do love the overall build quality. The case has some serious coating that seems completely scratch resisitent and the sides have a nice rubbery feel--cool color too!

I wish the screen had a higher resolution, but, once again, it's not bad.

Aside from this thing being outrageously expensive, I highly recommend it as an all in one GPS-PDA-Multimedia device.

Summary: I was going to purchase a laptop but my PDA took a dive and needed a replacement. I also wanted to be able to connect to the internet when I travel and I liked the idea of having GPS capabilities.I looked at other Mfg's like Asus and Palm but none could match the price and features of the HP rx5915. I have been using it the past few day's and it has been great. I personally don't know why anyone would purchase a $500.00 standalone GPS without first considering the rx5915.
