Certainly the size is not to everyone's taste but I myself would like the 5 "not to miss. In my opinion (and experience) after it is your pocket fit, but everyone should judge for themselves. The fact that it is so shallow, it no longer falls on as a "normal" mobile phone. But the difference even from 4.3 to 5 inches in usability is enormous. You can see either more or larger, thus browsing more fun.
The display is easy to read even in bright sunlight. The battery has the evening with permanent mobile data connection (mails every 5 minutes) and while driving Bluetooth connection (2 hrs. With 15 min. Phone call) in the evening (after about 13 hrs.) Btw. 80-70% residual capacity ,
The "plug" is, moreover, no in-house development of Dell but corresponds to the PDMI standard, which for example also uses the new Samsung Galaxy Tab. Because surely even more devices (also from other companies) are added in the future.
Price I'm going with "fsama" absolutely not in conformity, especially since the Streak cheaper than the Desire HD (4.3 ") and the Samsung Galaxy Tab (7"). Android 2.2 is also available for the Streak coming.
