I used to have a Qtek 9100 somwhere a year ago.Now I`ve just bought a brand new HTC P3300 (known as well as"Artemis").
First, I liked the superiour design - this PDA is one of the most beautyful and nice on the market.
Moreower , i really enjoy the unique RollR trackball system - it`s awsome.Surely, it is easier (at least if you are not used to RollR trackball or similar)to use a QWERTY keyboard, like in Qtek 9100, but dont forget:this makes any model bulky(except new HTC P3350,wich I`m goint to taste on later ;-) ).
One of the minuses is the processor: 200MhZ, but actually it is enough.
EDGE works great!Internet just "flies"!
WiFi system is also good.
Hard to get some maps for TomTom(1 offered for free to download),at least if you`re not in Britain,france or Russia, for example.
My conclusion: this device is recommended for those,who`ve already had any modern PDA,especially Qtek.For novices it will be a bit hard to get on with some functions and settings, but actually,if you`re able to read,everything is very simple.
So, calling all PDA lovers:you won`t find moe beautyful,qualitative and full of functions PDA for this reasonable price!
