I am on a newly purchased HP Pavillion dv6. I paid $750 back in July. It's fairly impressive, much faster than the machines I have in my work lab. I've been in IT for 10+ years, mostly on the hardware side. I just moved to software support and testing a few weeks ago.
Do you have experience with Apple? Not to much different than PC, but there is a slight learning curve, just to get used to what's different in naming and location, etc. From it what it sounds like, an Ipad might be a good buy for you. It'll be small enough to carry around, fast enough to surf the web, and easily process and store workouts and charts. Restrictions would be no network cable port(I think it's only wireless), no CD tray, small screen, lack of audio power, additional keyboard to carry if desired, possibly a few more.
I can't say much else about the Ipad, as I don't own one. I would give either the model I referenced up top a look, or maybe for a bit more the new Intel Ultrabooks, another pretty good recent release. My laptop has Win 7, running on a 3rd Gen I7 CPU with 8GB of memory, with a hybrid ssd/sata hard drive for extra boot speed. I'm at my desktop in 15 seconds from a cold boot. You might not need all those stats, but the lower model HPs are also pretty good, but less specs for a lower price.
