"maybe that number will be halved"
Simple calculation, if iPod is 20 million units, Archos is 1 million in 2007, then 1/20th. Though Apple might be closer to 40 million. I'm not a fan of reading through Apple press releases, if you want to know their forecast of number of sold iPods in 2007 you can go read their press releases and come back here when you have precise numbers for ipods sold.
"approx. 4 million PDAs in 2007"
Wikipedia and tons of articles talking about PDA sales shrinking the last few years.
"by 2009 smartphone sales of 100 million"
Smartphones are 60 million today, growth till 2009 is projected to be 100 million. It makes sence, email/contacts/calendar and such is cheaper and cheaper to do and so is 3G and HSDPA cheaper to do so there'll be larger sales.
"Archos sold 500,000 units"
Look at Archos 2006 sales press release, divide that number by approx average of 200Ôé¼ revenue per unit.
"1 Archos for every 8 PDAs"
Calculation, PDA 4 million, Archos 500 thousand, use a calculator.
"an HSDPA 606"
More than 12 official press releases talking about 3G+ which is HSDPA, look for them yourself if you don't trust me.
"UMPC sales lower than Archos"
UMPC sales for 2006 was 500 thousand. There are articles, if you cannot find them then I'll look for them again.
"2007 global UMPC sales at 700,000"
2007 forecast is something like this:http://www.umpcportal.com/journal/2007/ ... casts.html
Not to start a fight with you Charbax, but they asked for refrences. Not generalizations. "More than 12 press releases" is not a refrence. It is just a "claim". Can you hook us up with some direct links?
