The Nexus One will (probably) be officially announced next week. With any big smartphone release comes a plethora of peripheral devices. While none have yet been announced for the Nexus One, we do know of at least one company who intends to try their hand at making some. As Android and Me reports, accessory-manufacturer Seidio has announced that they will be launching a variety of gadgets for the Nexus One. In the company's own words; "We will have the ultimate accessories for the ultimate Android phone."If you visit their website you can sign up for their mailing list like I have. The company will inform you the instant they start actually carrying Nexus One accessories. Until that point, we can look at their line-up of Droid peripherals for a clue as to what we can expect. Screen protectors, holsters, and impact-absorbing cases are all a given. We'll also probably see extended battery packs and a desktop cradle or two, possibly also a phone dock/speaker set combination.
