I'd still be using my Apple II+ !!! :P 48 MB RAM. Green Screen. What's a hard drive anyways? Never heard of one. At least then we hadn't.
I guess the whole point to this thread is that you try to jump into the game at an oportune moment. Looks like we jumped in a couple of months early. Oh well. If you would have waited for the PXA250 C1, 200 MgHz bus, guess what. Intel will anounce the PXA255 one month after that one comes out. Intel releases that one, then they announce the next. It's a never ending cycle (BTW, someone pointed out to me on another post that this is called Moore's Law).
Utilize what you have to the fullest of its potential, then when it no longer performs the functions that you require it to, buy a new one. I think the Dell Axim X5 will the functions required by 99% of it's users.
But hey, if the D-pad just happens to break on your Axim the week after Dell starts shipping the Axim X5 including the PXA250 C1, 200 MgHz bus, what can you do??
