Farmer 1....
Don't know where you got your Tosh experience from, but I've never had a problem getting things sorted out. Then again, my experience has been with their business notebooks, not with the cheap and nasty stuff that can be found at certain high street retailers.....
That said, if you want top notch support on a PeeCee, I would suggest HP (again, business range, not "retail") and buying an HP Carepack (note I said HP, NOT a worthless [insert retailer's name] extended warranty !).
However, I've got a MacBook Pro with 4GB of RAM, WiFi, BlueTooth ..... Apple support is generally very, very good ...and because the all Apple laptops now have intel processors, you can run Windows at full speed in an emulator (or on full hardware with Bootcamp). I wouldn't go for the MacBook Air, but that's only because I need a proper ethernet port, not some USB dongle.
Your mileage may vary ...all just my 2p worth.
