Raspberry pi 2 processing capability?

Hearing the announcement of the new latest and greatest Raspberry Pi 2, now a backwards compatible computer with a 0.9GHz ARM Cortex-A7 quad core processor and 1GB of LPDDR2 SDRAM, I was wondering of the feasibility of using it as a very cheap and basic solution for a simple computer for my lab.

Currently, I am using a compaq presario C700 Pentium Dual-Core laptop, that has been maxed out with 2GB 800MHz kingston RAM, and is running Kubuntu. I should also not the HDD has been replaced with a 120GB one from an old and broken Xbox. I do not like it much anymore, because although the performance of it is acceptable, the screen is a bit low res, at 1280x800, it's pretty dark (or at least until it 'warms up' to full brightness), it had a major scratch on the screen, (no idea how it got there) and after buffing it out with many methods, including with an eraser, the area has became discolored, like a portion of the screen has higher gamut and brightness, and lower black levels. :( Oh well. The main killer for it is that it's form factor. It is too big, heavy, the screen is too small, and it is very cumbersome to use far away in the corner of my workbench. Of course being a laptop, the 'base' of it is fixed to the screen, and to move it closer to me takes away lots of valuable space on my really messy bench.

I mostly use it to research part numbers, get schematics off of google, watch YT videos, log data from serial ports (including my UNI-T multimeter with basic data-logging capabilities), and stuff like that. I may have as many as 20 tabs open at a time, which did tax my old compaq C700 when it had 1GB of RAM, but that was likely due to a memory leak issue with chrome, since I have the SAME issue with my main desktop, with 8GB of DDR3 RAM. If the video by MAKE is anything to judge, it looks just as powerful, as this embedded video is large!

My hope is to replace it with a raspberry pi, and be able to use it for these basic operations w/ a old LCD monitor which can be picked up off of craigslist for cheap. Maybe I can even find one in the dump :P. Maybe I can configure the GPIO pins to be COM and parallel ports, w/ clock, Tx, Rx, and everything else! That way an external FTDI chip and using the limited number of USBs is not an issue. Is that possible?

We're using the Pi 2 at work, we bought kits of bits for me and others in my team to play with. The Pi 2 IS significantly faster than the 1.

Would you reckon that it is powerful enough to run many tabs open in Chrome, including a youtube video in 720p, and maybe LTspice?

What's this ? One reply per processor core ;-)

4 replies is within the bounds of the Pi 2 quad core processor! :^)

Your not asking a realistic question - Most operating systems will run multiple tabe - BUT some faster than others = the Pi is still a CHEAP 900 Mhz processor. Buy one and try it. For £20 - £30 how can you lose.

I don't know how much more practical and realistic the question can be: Under optimum conditions, with the most resource-efficient OS installed, probably one of the offered linux OS that has been modified by the developers to make use of the custom hardware, would it be possible to do what is asked above. I can imagine that LTspice, which is probably compiled to work on x86 architecture, or something like that, the intel/AMD desktop arcutectures, anyway.

6 times if the advertising hype is correct.

A lot depends on what you expect it to do.

It's about as fast as an old At pc.

They do have some good applications my son runs a pi 1 as a music server manages his music downloads and replays throughout the house.

He is however a programmer.

There is a lot of pi based programming around and the python library is quite big. For the cost you should really try and see if it suits your purpose.

I have a Pi 1 and I do not believe the 2 can even come close if by some magic chance you could ever find software to perform your desires.
