You know, Apple could have convinced me to give their machines a go (albeit removing OS X for Vista) had they engineered the MacBook Air correctly. Instead, they produced a glorified PDA (aka UMPC) that really isn’t all that useful. After the specs first starting appearing on the keynote feeds, I immediately thought of the Sony X505 which I previously had drooled over. Indeed, Sony noticed the parallel too.
Anyway, I do own a ThinkPad X40 which is a pound lighter than the MacBook Air, has a removable battery (with multiple options and with the UltraBase, up to 11 hours on one go) has a reasonable amount of USB ports, does not require any dongles to use, a PCMCIA slot, an Ethernet port and a full set of accessories including an external optical drive or snap-on UltraBase containing another battery, hard drive and optical drive.
Additionally, you get a very nice warranty that doesn’t require you make appointments and drive an hour to the nearest "genius bar" for assistance — instead Lenovo sends you the necessary parts overnight on a 24/7 toll-free line with little hassle (yes, personal experience).
Oh, did I mention it was $700 cheaper?
In order to promote this better way of computing, I have produced for your entertainment the first ThinkPad Air commercial:
Note: the manila envelope makes a decent case, I might keep using it regularly…
