I like them, but then I like Handsprings in general.
Be aware that there are two versions - the 180, and the 180g. The 180 comes with a mini qwerty keyboard as the main input method, the 180g uses the 'traditional' Graffiti method. The Novatech version seems to be the 180.
It is a bit big and bulky as a phone, but the combination of a full Palm (Handspring) PDA and a phone in one package compensates.
It requires extra software (freely available) to use with MAPI mail servers, but works just fine with POP3 mail.
Browsing is fast and easy for a mobile device. The ones I bought for work were about £600 without a SIM / contract - £120 is a real bargain for a full PDA and phone combined.
