I'm sorry but this Streak is garbage. It's just another Android phone, locked to O2 probably, so will have limited distribution, has to compete with iPhone HD released next month, sure, it has Flash, but it's a Dell, it's not big enough to even be a tablet, and it's too large to be a reasonable smartphone.
I call Fail on this one.
As some posters mention, nothing to see here, move along, fangeeks will be all like, oooh, but I don't think it will be a netbook replacement, nor a smartphone nor iPhone nor Blackberry replacement.
If I were a Dell shareholder I would wonder how many hundreds of millions of dollars in R&D, marketing, etc. was just pissed against a wall.
Blackberry, I can respect as a suitable alternative for those that don't think iPhone is suitable for them. Other Android phones, maybe some out there are reasonable and people like using them, good for them. But Dell, in this market space, with a neither-here-nor-there, thing, I think is utter crap.
Dell obviously didn't have the balls to go all the way with a 10-inch ACTUAL TABLET for fears of losing sales of their netbooks. This is just a, "look we're cool too... Stop switching to Macs, Dell is here, we're cool, we're hip, we're Android, we're Froyo'ed YEAH baby...".
I had the displeasure of actually trying to use a Dell Axim about 7 years back. What a absolutely horrible experience that was.
