Well, the ZTE Blade is one of the most interesting smartphones around.
I say interesting because it's earned the unofficial status of "The People's Smartphone". Here's a quick rundown of ups and downs about the actual device:
First the bad:
-Camera is below average, takes decent photos in broad daylight and that's about it, video recording quality is mediocre;
-Features a ton of bloatware, regardless of the carrier (rooting the device is mandatory);
-Low Internal Memory, 200 MBs is very little since the OS already eats up a huge chunk of said space, I recommend having a Class 10 Micro SD card in there to Create a Partition;
-Weak CPU, but then again, this smartphone is nearly two years old;
Now the good:
-Very accessible price point;
-Overall the best smartphone under 100€;
-Has various indie teams making custom ROMs;
-Can run Gingerbread and a few custom Ice Cream Sandwich roms;
-Sleek design, good grip, overall good construction;
-Great OLED screen;
-Good touch quality;
-Wi-fi is very good;
-Runs a ton of great apps;
-Lightweight;
-Good battery life;
Though, to be honest, there are a few alternatives to this one, or so I've heard, like the Huawei Ideos X5. Which is slighty more expensive.
But I'm just waiting for the ZTE Blade III to come out. It's been out since September but I don't know when it'll be sold in Portugal and which of the three major carrier will provide it.
