how does it handle large PDFs? 

I am a graduate school student in the market for my first tablet but I feel very overwhelmed with the options, o/s and models on the market.  

I primarily would view pdf/powerpoints, school related websurf, listen/record audio of lectures, view, type, & edit word/text files – preferably with USB keyboard since I am uncertain about touchpad typing & USB option for jump drives or data transfer between systems.  I currently don’t care so much about screen resolution, cameras, 3G/4G, watching HD movies or using it as a book reader, which seems to be what most of the tablet reviews talk about.  

It would be great to get something sturdy in case I drop it and I don’t mind paying for quality.  

That being said do you think anything the market fits my bill or should I wait for one of the tablets that are about to come out like the ASUS transformer Infinity?  Fujitusu Q550 caught my eye as it seems rugged, security from theft, and it is running Win 7 (for compatibility w/my current file library) but then do I have to worry about viruses & trojans?

I dont mind buying an older model (Xoom, etc) as well or waiting a little longer for new releases.   Can you give me some ideas out there anyone?  Thank you!

I returned 4 of these le pan II’s they all had bad pixels, and the screen brightness degraded only after 2 days. Nice features but very poor build quality. I then bucked up and got a real tablet. iPad 2 on sales for 359.00. If your on a budget get the aniol novo elf II. Better specs than le – turds II and at a price of $120 to $160.

I really like this tablet, but I don’t see this price to performance value when comparing with this..

Have had my Lepan for 6 months and like it. When they were released they were absolutely the best deal for the money around in Q1 2012 but the market is catching up, so is not quite the “no brainer” it used to be.
Pros: I bought mine for $249 and have not regretted it.
Build quality is good, and the extra weight seems to have been translated into a fairly robust unit. I dropped mine a few times (once without, twice in the case) and it has survived well. I cart it around all over the place and let my 3YO use it and the case is still stiff and no flex. I got a “soap and water” screen protector which has been great. Before that fingermarks drove me nuts.
Sound is good and the screen is no retina, but is still bright and clear. Touch screen works quite well (takes a few seconds to “wake up” after it has powered down – often need to put password in a few times) ICS release was reasonably prompt – a lot of online moaning about it in part because they promised ICS for the TC970 and never delivered, so there was a fair bit of scepticism about them. Cons:
They can be buggy. There is a common problem with the power button (which seems to be a software glitch, not sure if it still happens after an ICS upgrade.) Some reset when linked to a computer. A few resets when using apps, but not common on mine. Battery is only just OK, but no worse than many other tabs that cost more.I bought mine from an international website and used a freight forwarder to get it to OZ. I did not have any problems/returns, but a lot of people have so I would have to say I am a bit lucky. Based on online comment they seem to be good about replacement but not that responsive to queries. The charging cord is an annoying 30 Pin. The one supplied was 10th rate garbage that broke within days, leaving me high and dry as they will not ship me a replacement outside the US/Canada. Had to mod an ipod cord which works well enough. Overall, would not rave but am a satisfied customer. Priced under toshiba / samsung they are quite comparable in quality. Good hardware, the Android build shows the signs of being a small production team a bit stretched. Once the Le Pan III hits the market they will no doubt drop the II like a hot turd, so don’t count on much ongoing support.

UPDATE – Le Pan II dead after 10 months. Just bricked itself overnight. No point in shipping it back, just writing off as a bad deal and getting something else.
