Received my iball 7334i tab yesterday through WS retail.it has dual core processor and 1 gb ram that is responsible for its swift performance.No lag even using 4-5apps simultaneously + Update going on through wifi.bulid quality is pretty decent although back panel is made of steel and is slippery to use but its ok.sound quality is nice with dual stereo speakers present at the back panel. Camera quality is pretty ok. Its comes with lot of inbuilt apps including WhatsApp, wechat, file explorer etc.one important feature that has impressed me a lot is 16gb internal memory. Battery backup is great I used it continuisly on wifi for around 4-5 hours wuth heavy downloding and its consumed only 50-55% of battery.i must say this is the best tablet within 10k
