Cons: no USB sync&charge cable, yellow screen effect, included software is ok

This will be a fairly short review as there are numerous other sites out there (eg. brighthand, pocketpcthoughts, etc) that have some excellent detailed reviews. My perspective is more from a 'average Joe' view and will skip the details on processor ...

Pros: WiFi Bluetooth capibility Size
Cons: Battery life still isn't impressive!

After upgrading to a HP 1945 for only 6 months, I really wanted to have WiFi access. I thought it would be great to be able to check my e-mail and visit my favorite sites without booting up my desktop. Also, since I have a wireless LAN set up at home ...

Pros: Fast, sleek, good bluetooth and wifi, good onboard memory.
Cons: Battery life a bit limited.

I love my new iPAQ. It is sleek, fast and powerful. I really enjoy the form factor as it fits comfortably in my pocket throughout the day. It is very fast changing programs. Wireless and Bluetooth setup and usage has been very easy and I have connected to hotspots in Canada, the US and Europe. Battery life is a bit limited, but I purchased the extended battery which has worked very well. It does add a bit to the weight but still fits inside the HP-supplied case and is very comfortable to use. I use the reference software I have installed extensively at work all day, and stream music wirelessly from my home network in the evening.
The iPAQ 4150 is simply awesome.
