I've been running a laptop for at least a decade now.
I use it with Quicken, NOT wi-fi though, the service area here is lousy but getting better.
I use it in conjunction with a Canon Pixma portable printer.
I print out invoices on the spot, it has my banking details on the bottom of the invoice so people can pay immediately.
Commercial clients email at the end of the day from home.
Next financial year, (July), I WILL be going to a Samsung tablet wi-fi and still carry the Canon printer.
I also use Paypal to collect via card when reception is okay.
Trying to lighten the load on everything I have and carry.
