interesting as this issue might be, its not what the thread is about guys.
So - back in thread, i still use my laptop but far less. i find myself typing up estimates on ipad then forwarding via email to format within Word before sending to clients, and tbh those i know well get just the rough copy so to speak.
I found being less formal is being seen as more approachable and friendly, while the work i actually do is known as always professional.
many iOS accounts packages exist, but none offer all i need, VAT cash accounting scheme as example removes most from selection, others handle it at invoice but do not offer a reasonable VAT 100 report, so the laptop is used for accounting.
I use several programs to work with telephone and alarm systems, no option but to use a laptop, but i can get onto Tv DVRs via WiFi and set them up, or use my iPad or phone as a service monitor over the internet when setting up cameras far easier than a laptop.
