It's a fair few more than that if you count the ones available in the US.
Which are just rebadged versions of phones over here, either way there HTC WP7 phones over there that aren't over here too.
Or people will look at other people's higher spec Android handsets and realise, like most technology, you get what you pay for. So next time round they may invest in a higher budget Android handset.
You overestimate the intelligence of most people I think. To them they probably don't realise the higher budget android handsets are higher budget (or care) as they get the one that comes free with their package.
Either way cheap, poor performance handsets will have a negative impact on the Android brand whichever way you look at it.
You've minimised you're view to only the UK market. If you check any Android site, they're littered with new devices and rumours about Android phones built by HTC and Samsung. I think you'll find there are currently around 20 Android handsets that HTC built (including those that are no longer manufactured).
My initial point in my first post: HTC and Samsung are concentrating on Android (evidently). Nokia is a HW company, MS is a SW company, this option appears viable for Nokia to choose WP7
Ahh, so we're including phones no longer manufactured? In which case I guess I can include all the WM phones in the list too... So that's around 100 I guess...
There's a reason I specifically said ones manufactured at the moment. You can't really suggest a company are concentrating more on one thing than another by citing things they used to sell!
Lets put it another way. Lets compare the number of phones released in the last 6 months, Android and WP (reasonably fair considering we're talking about what currently concentrating on).
That's 5 WP7 devices worldwide (Add HTC surround) and 4 Android phones (HD, Z, Mytouch and Gratia (never heard of that one!)).
In fairness to Android there were 7 other Android phones released in the last 12 months and one WinMo device.
In comparison (because I think it is reasonably fair to compare) since Android was released at the end of 2008 HTC have manufactured 16 phones. They manufactured 22 WinMo phones in that time.
As I said HTC definately aren't concentrating on Android to the expense of WP7. It'll be interesting to see what MWC and the next few months bring up as it's not that fair comparing an established ecosystem to one that is only a few months old (ala WM and Android).
Samsung are not much different, they released 7 Android phones in the last year but none in the last 6 months, whereas they released 2 WP devices in those 6 months.
EDIT: Having said all that I don't see HTC releasing a new WP device at MWC because they have all the bases covered with pretty new phones (4 months old) and cannot release budget ones due to the restrictions put on them by the WP minimum requirements. Obviously Nokia building WP7 phones would increase sales numbers of WP phones, because that means more manufacturers, but to suggest that they would take the horns moreso than HTC and Samsung is a little stretching...
