I remember very clearly when webOS was announced. I was still living in Italy and not working for Google yet, Android was far from being as popular as it is now and I personally believed webOS was going to be a huge success (I also applied for a job at Palm, but that's a different story).
The announcement that HP will discontinue production of all webOS took me by storm. One year passed since Palm was acquired for $1.2 billion and less than two months since the launch of the TouchPad, the first tablet running webOS.
When the TouchPad finally came out it had a very hard time gaining traction against strong competitors like the iPad and all Android tablets. Price was too high to convince people to give it a shot, however, declaring it a failure and selling all units in stock for 99$ (instead of 399$) was probably an untimely decision.
It took less than 24 hours for all online stores to sell all their units and some people were even camping outside Best Buy stores to get the 99$ tablet, so HP probably had to lower the price in advance to build the user base, instead of just giving up.
I managed to order one of those tablets, I never tried one before, but price was too good to let it pass. There are also rumors of an Android port for the TouchPad and its specs seem pretty good. I know there will be no new apps and no support, but if it runs a browser you can still do almost everything, can't you?
Have you tried webOS or the HP TouchPad? Have you considered buying one for 99$?
