The Samsung Galaxy Wi-Fi is basically part of the Galaxy range of smartphones but lacking the phone part, much like the iPod Touch is an iPhone that can't make calls. It runs Android, so you'll have apps, music, videos and games, as well as the whole internet wherever you can find a Wi-Fi connection.
We first spied the Galaxy Wi-Fi back at CES, and were mightily impressed, as it looks like it could well be a worthy challenger the iPod Touch's MP3 player crown. The 5-inch model is on sale now for us Brits, while the 3.65-incher will hit shelves next month.
Both sizes of Galaxy Wi-Fi run Android 2.3 (Gingerbread), which is optimised for tablets, so you shouldn't have any issues on the larger screen. Both also have 1GHz processors inside, but they differ on the cameras; the 3.65-inch model sports a 2-megapixel fixed focus with LED flash, while the 5-inch one has a 3.2-megapixel with auto focus and LED flash. Both have VGA front facing camera for video conferencing, so better look your best.
Both come with a host of preloaded apps, like Gmail, YouTube, Google Latitude etc. (and you can download thousands more from Android Market), as well as an accelerometer and digital compass. Both sizes come in 8GB and 16GB versions, so nowhere near as large as the 64GB iPod Touch. The 3.65-inch model costs £149 for the 8GB, £169 for the 16GB, and the 5-incher is £199 for the 8GB, £219 for the 16GB.
We had a hands-on with the Galaxy Wi-Fi last February, and were impressed with the large and bright screen. Whether 5-inches is too big for some to carry round, and too small for a tablet, we'll find out pretty soon. Samsung is obviously backing the size though, as it's also launching the Galaxy Note at around the 5-inch mark.
