That's a fair business decision - can't fault MS for that. One division that is looking to extend it's reach should not be confused with another that can't sell phones.
On the bright side of being a Brit consumer in the mobile (cell) market I can always choose to be done over by a home grown firm (Vo(ice)da(ta)fone) from Newbury whilst using a foreign manufactured device that sucks my eyeballs out. Or I could be done over by a foreign firm with a foreign device. Thankfully I have choice - I know of several countries that don't even have that.
