Out of all the "other Pads" I've tried at the store, the HP one is the best, but not enough Apps....
I agree. I had a chance to play with a variety of tablets the other day at Best Buy. I owned an iPad (sold it when I got an iPhone) so I'm certainly familiar with that. I liked the TouchPad. I liked the PlayBook slightly less. I wasn't so impressed with the Android tablets, nor with those Windows 7 tablets (nice, but so thick and heavy...)
Someone either here or on Engadget likened this to the beginning of the PC revolution. Remember the early 80's when everyone started to come out with personal computers? You had the IBM PC, Commodore 64, PET, Vic 20, the Apple II, the TRS-80, the Spectrum, ... every single one of them was similar to the next, but not compatible.
Which one won out in the end? The one with the biggest business software support. All of them were equally great for hackers and tinkerers but it was VisiCalc, Lotus 1-2-3, etc. that spurred business adoption of some devices over others. One or two brands survived and grew -- the rest just disappeared.
Given the parallels, it looks most likely that Apple and Android devices will be the ones to survive the tablet wars... there will be a lot of "me too!" devices but how long will they last?
