Is HSDPA backwards GPRS/3G compatible?
I am looking for a lightweight ~ 12" laptop which has wifi and gprs/3g built in and has a ~6hr battery life.
The IBM/Lenovo laptop ThinkPad X60s 1704 lists as having HSDPA. This appears to be a superset of 3G. It's a pretty unusual option in a laptop.
Does this mean that it will also work on 3G and GPRS? I've written to Lenovo but no reply as yet.
What about fax? Fax is specified in the GSM spec and most GPRS cards do support it.
The other thing is that Insight are bundling this laptop with the Vodafone GPRS/3G PCMCIA card. What is the point? It could be just stupidity; they offer this Voda card (with a silly ~ 10/MB PAYG tarriff) with loads of other laptops as presumably they get a commission on the calls. The card is close to worthless; they are on Ebay for £30.
