Remember when I said Sony Ericsson should give up on phones, well I might’ve spoken too soon. The new Sony Ericsson Arc, a 1GHz gingerbread device that was announced at CES is that device I might have judged too early. This new Android phone was reported by Engadget as being a pleasure to use and apparently not sluggish like its older brother the X10 was. As far as updates go, Sony Ericsson promises to give you updates in a timelier fashion, unlike the X10 that’s still in 2.0 land. Regardless, this is an impressive device.
