So many people post here asking for recommendations of PC laptop models that will work well with audio hardware/software that a sticky thread seems like a very good idea.
However, please remember that a personal recommendation, however honest and heartfelt, doesn't guarantee that someone else will have the same positive experience, or that a different audio interface may have problems, so take care out there.
Please use this thread as far as possible to post details of a model that you have that you would like to recommend to others, and why, rather than posting loads of queries. It will help greatly if you include:
1. Make and model.
2. Processor type & speed.
3. Amount of RAM.
4. Drive(s) capacity.
5. Make and model of audio interface
6. Interface connection type (USB 1.1, USB 2.0, Firewire, PCMCIA, PCI Express)
7. Main software used.
Let the recommendations commence!
