Raspberry Pi Makes a Painfully Slow Desktop

I couldn't help but be a little intrigued by all Raspberry Pi hype.  A computer smaller than a deck of playing cards, able to run Linux/ChromeOs/etc. and costing only $25-35 (depending on the model), sure sounded interesting.  There are no end to computing projects I have in mind to undertake, so this seemed the perfect platform for them, particularly when the Raspberry Pi community is so friendly and supportive.

Well, having had my Raspberry Pi (model 2) for a week now I can certainly say that it's cool alright, but I'm increasingly convinced that its use in the desktop-related computing projects I had in mind is severely limited.  The official Raspberry Pi Debian release runs, and includes a resource friendly web browser and other resource friendly apps, but attempting to run anything else is painful.  One project I am working on uses JonDo, the magnificent privacy proxy, so I tried to see if the JonDo client would work with Raspberry Pi.  It does install, and run, but it is painfully slow as to be utterly unusable (perhaps because of the Java overhead or perhaps because of the encryption demands).  So much for that.

The thing I love most about the Raspberry Pi so far has less to do with it and more to do with the discontinued Motorola Lapdock.  A couple years ago some people at Motorola and elsewhere thought that what people really wanted was a way to use their phone as a laptop and I remember all the hype surrounding the "lapdock" which would let you do just that.  Unfortunately, at a price of $500 people really didn't want it, opting instead for cheaper $250 netbooks and $250-600 iOS/Android tablets.  Sad for Motorola but great for anyone now because these over-produced lapdocks have been hitting the deep discount sales sites for the last year or so, currently selling them for $49!  What you get for $49 is a fabulously elegantly, slim 10" display with keyboard, touch pad, and built-in rechargeable battery back!  I seriously know of no better tech deal ever!  Now, the cool part is that rather than use some proprietary connectors the lapdock uses separate micro HDMI and micro USB connections, and being universal standards you can connect a Raspberry Pi or anything else you want up to these connectors!  I bought a second Motorola Lapdock to use as part of my emergency computer repair tool kit, with this thing and a few cables I've got a mobile keyboard/mouse/monitor I can hook up to any down server or computer with questionable peripherals.

In the case of Raspberry Pi this means that for $49 (Motorola Lapdock) + $35 (Raspberry Pi model 2) + $10 (cost of cables) you have a $94 laptop.  Admittedly it's a pretty underwhelming laptop in a field where vastly more powerful laptops can be had for just over $200, but still...  If you're buying a Raspberry Pi for anything other than experimenting then you're doing it wrong.

Watch the video above to learn what cables you need and how to modify them; the girl in the video throws me off a bit, I think it's the Ferdinand the Bull nose ring and reddish hair.  Also, check out this cool modification to learn how to add a super capacitor to your Raspberry Pi as a great little backup battery/brownout protector (which is particularly useful with the lapdock).
