I bought myself a Samsung Galaxy Tab 2 during the tax holiday. The low price store, Best Buy, had it for $167 before the holiday, then raised it to $179 during the holiday, and now has dropped it back down to $169. The effect of the price increase was to eat up most of the savings that I would have experienced from the holiday had the price remained the same as it was the day before the holiday.
I was going to buy the tablet anyway, but the tax holiday itself did not benefit me much at all.
One piece of good news is that Best Buy (or at least the store where I bought it) is offering free classes on the Android OS, so I hope these will prove beneficial.
