Of course Nokia has just gone through a "refocusing of the device nomenclature structure", as evidenced by the Nokia 600, 700 and 701 Symbian Belle devices, which have been warmly received by many, including The Next Web, which has taken a look at this issue for Nokia returning to a familiar numerical system, just as Samsung switch to a name and letter system that echoes the E, C and N of the current Symbian line-up.
What's more important to you, an over-arching name like Galaxy, or a clear guide to where a phone fits into the line-up (as you used to get with the Nokia 7600, 9210 and 3650)?
