That's right, there's another 7-inch tablet to tempt you, with the Kobo Arc now on sale in the UK.Specifically, this is on sale in WH Smith, which will be doing the hard sell in the run up to Christmas in its stores. Good luck with that. With the Google Nexus 7, Amazon Kindle Fire and iPad mini heading up a very busy sector of the tablet market, the Kobo Arc will have its work cut out. But as ever, it is horses for courses and price will also be a key factor.With the Kobo Arc, the price is £160 for the 16GB model and £190 for the larger 32GB tablet. For that, you get a 7-inch Google Certified device running Ice Cream Sandwich (with a potential Jelly Bean upgrade to come), complete with a 1.5GHz dual-core processor, 1GB RAM, Wi-Fi, a 1.3-megapixel front-facing camera and front-facing speakers. Access to the Google Play and Books stores is obviously included too.The Kobo Arc is priced similarly to the Google Nexus 7, so you probably want to do a comparison with that tablet before you buy. If the Arc comes out on top, it's available to buy instore now.
