I purchased this ACER Tablet 18 months ago and it is now out of warranty. While it was working it had good performance and I was very pleased with it. Now suddenly, the ON-OFF switch on the tablet does not make the faint, mechanical sounding \"click\" that it use to make when pressing it down to start up the tablet. As a result, I cannot get my ACER A500 to turn on at all, which makes it an expensive paper weight at best. All this wonderful 100% functional solid state technology inside the case and a poorly made, inexpensive on-off switch breaks down and makes the whole system USELESS. Such a switch should be the BEST micro switch money can buy since it is the one switch on the tablet that users press over and over again. Alas it is not to be. I'll never buy an ACER product again and I would highly recommend that you do not purchase this particular tablet at all.
