I'm in the same situation as you. This is perfect. 2021 feels so far away though!

Been using this as an ST2 package for a while. Works great.

I bike ~40km per day in London, from near Richmond to Tower Hill. It takes slightly less time than the tube, and it's a lot of fun.

Rain makes it more fun. Just stop caring about getting wet clothes and buy a backpack with a waterproof cover.

Dammit, just bought a MacBook Air a month ago. Is there much difference between the 1.4 core 2 duo and the 1.6 i5?

Yes, quite a bit:

Win! Spoke to Apple, they are going to refund and take away my 16 day old MacBook Air so that I can order the new one :) Excellent customer service once again.

It's a win unless you don't care about the downgrade in graphics performance (nVidia > Intel GMA) and power consumption (Core2 > i7). In these regards the latest model looks like a downgrade, at least on paper.

I'm appalled that noone seems to notice or care about those things, especially power consumption.

Graphics performance: http://www.notebookcheck.net/Mobile-Graphics-Cards-Benchmark... search for "NVIDIA GeForce 320M" and "Intel HD Graphics 3000". Intel has a history GPU's with poor perfomance and feature support.

Power consumption: on this very table, look at TDP http://ark.intel.com/compare/54617,54618,56858,36697

Pentium M(2004) = 5W http://ark.intel.com/products/27609/Intel-Pentium-M-Processo...

Core2(2008) = 10W

i7(2011) = 17W

Despite the shrinking of the electronics Apple even had to raise weight a little in the latest model, to accomodate a battery large enough to provide the same "5-7" hours of runtime. That's when you are mostly idling or browsing; I'm sure the new Air will run hotter and shorter if you utilize your CPU closer to 100%. Well, customers want an "upgrade", and there are no better parts available; what else can you do?

Interesting that the wattage is much higher. Does this mean that a bigger battery was required (possibly explaining the minor bump in weight)?

Yep, the battery was bumped from 40-watt-hour to 50-watt-hour.

This blog post sums up exactly why I wouldn't start a web agency.

Surely this is just common sense at this point?

Woah I'd completely forgotten about K10K! (from http://37signals.com/23)

That was it? One more thing?

I'm self-taught too, your comment really resonated with me. I'm a contractor so I'm always having to try and figure out what "level" my peers are at. Once I start to get to know people though I start to realise that they usually have the same self-doubting attitude as I occasionally do.
