You mentioned buyer's remorse. I am willing to correct this by purchasing the replacement hardware that you recommend for the following requirements:
Let's say I want to buy a subnotebook computer (a laptop with a 10.1 to 11.6 inch display) to run HTML5 vector animations, GCC, and Wine applications inside GNU/Linux. (Wine requires x86 or x86-64 architecture.) I also want WLAN, Bluetooth, audio, and suspend to work. Which subnotebook computer brand is any good nowadays?
