It looks as if HP has brought back the iPAQ with a boom, as it has announced five different series of new handheld devices. Please note that all the links below are to PDFs.

First up we have the iPAQ 900 series which are 3G messenger phones with a front mounte QWERT keyboard. It's powered by a Marvell PXA270 processor at 520MHz, 128MB RAM and 256MB ROM, has a 2.46in 320x240 touch screen, Wi-Fi, Bluetooth 2.0 with EDR, GPS and a 3Megapixel auto focus camera. More here

Next up is the iPAQ 600 series, which again is a 3G handset, but this time without a keyboard. It features the same processor, same ammount of memory, a slightly larger 2.8in display with the same resoution, Wi-Fi, Bluetooth 2.0 with EDR, GPS and again a 3Megapixle camera with auto focus.

Then we have the iPAQ 300 series, which is a travel compantion running Windows CE 5.0 with a custom HP front end. This is not a phone, but rather a GPS navigator powered by a Centrality Titan 600MHz processor and it has 128MB of RAM and up to 2GB of flash memory for map storage. It has a 4.8in 800x480 display and it does of course have GPS, but also Bluetooth 2.0 with EDR. More here

That takes us on to the iPAQ 200 series, which HP calls an enterprise handheld. Again not a phone, but more of a classic PDA. It's powered by a Marvell PXA310 CPU at 624MHz, has a mere 64MB or RAM and 256MB or ROM. The screen is rather large at 4in and it's LED backlit and features a resolution of 640x480. The iPAQ 200 series also features an SDIO and Compactflash slot as well as Wi-Fi and Bluetooth 2.0 with EDR. More here

Finally we have the iPAQ 100 series, which is the most basic model and HP calls it a classic handheld (sound like they've been talking to Apple about the classic branding) and just like the iPAQ 200 series this is a traditional PDA. It has the same Marvell CPU, same ammount of memory, but a smaller 3.5in LED backlit display with 240x320 resolution. It's also missing the Compactflash slot, but retains the SDIO slot, Wi-Fi and Bluetooth 2.0 with EDR. More here

We're not sure what happened to the 500, 700 and 800 series, but maybe they'll show up at some stage.
