MobileTechReview reviews the Garmin iQue M3 with GPS, and finds very few cons (mainly, a battery that’s not user replaceable, and a short - 2 seconds - delay when programs are launched).

And the pros? There are a lot of them: “Lot and lots of space to store documents, applications, MP3s, photos and videos. It’s amazing how much you’ll want to throw on this device once you experience the freedom 4 gigs provides. The 320 x 480 display, supporting both portrait and landscape modes is higher resolution than most portable video players’ and is great for photo viewing. Excellent companion to a digital camera that uses SD cards. The excellent Pocket Tunes is included for your MP3 listening pleasure and sound through headphones is both good and loud. The desktop software makes it easy to transfer files, convert video and keep documents in sync. Works as a removable mass storage device, and you can use it like a flash drive with any computer that has a USB port (no driver required, just bring your cable). Wifi means fast wireless Internet access, and Bluetooth allows you to connect to your Bluetooth enabled mobile phone, GPS, keyboard and more. Battery life is quite good given the processor speed, large display and internal hard disk. The unit charges quickly. Data is persistent and will survive battery rundowns.”
