I can explain this, buddy.
Nov 2011: I guess SGT 7.0 Plus was released this month. I pre-ordered, and bought it before its official release date by Amazon.
Jan. 2012: Samsung announced Galaxy Tab 2!!!
Feb. 2012: Samsung released Galaxy Tab 7.7 & My SGT 7.0 Plus price dropped. I paid $400 for 16GB. Now you can buy $350 for 16GB or $380 for 32GB.
IT TOOK ONLY 3 MONTH to drop their price.
I TOTALLY agreed that gadgets price will be dropped soon after its released date. But, Not within 3 month.
So, what's next? Of course, Galaxy SIII, Tab 10.1" 2, 8.9" 2, Tab 7 Plus 2, Note 2 within this year? I guess so.
