As per usual - Apple have taken credit for an idea that wasn't theirs: the tablet
We saw it with the touchscreen phone too.
Take a little look at what was on offer before the ipad and the iphone - now take a look at what we have now.
Love 'em or hate 'em, they give the market the kick up the backside it needs from time to time. I don't think I've ever had an issue with no flash on the iPhone, and I've never noticed any difference in day-to-day mobile browsing when I use my Galaxy S.
Maybe people do buy iPads to show them off - they're an aspirational product.
We have seen a hell of a lot of Android tablets being released over the last year or so - none of them (aside from the Galaxy Tab) have shown any promise. They seem stuck on lower versions of the OS (Scandalous that any device should be released without the latest OS version, or a VERY prompt update) and some don't even have Android Market.
Google have openly said that Android is not meant for tablets - but given a decent update schedule and commitment on the part of the manufacturer, I don't see why not. The Streak is a really interesting device. I can really see how keeping it in a rucksack and connecting it to a BT headset would work. I think that's pretty cool.
The iPad will always sell pretty well. As with the iPhone, anyone with a tablet/touchscreen phone will get folks asking "ooh, is that an iPad?".
I'm not sure about Blackberry. I really love their handsets (for the most part), and I firmly believe there's no handset more reliable. I just wish they'd offer TCP/IP alongside their BES and BIS - not everyone wants/needs/has the network to use BIS or BES.
