Has anyone seen the price of an electronic go UP months after release?

So, I have been eagerly waiting my college disbursement to order a Sony Vaio Duo 11 to replace my iPad and aging MBP. I was excited and got it put into my cart on Sony's website and everything. Even got a 10% discount because I am a student, taking my total down $1485+tax for the top of the line model plus battery sheet.

Got my disbursement today and immediately went to place the order and noticed that the top of the line Duo 11 has gone UP from $1499 to $1599 in the past week! Has anybody ever seen this happen to an electronic device MONTHS after release?

Granted, it seems like Sony has had problems keeping this thing in stock, so they might have inflated the price of the top-line model to help compensate, but still!
